AB  - The structures of the first two complexes with bidentate coordination of aminoguanidine Schiff base, i.e., 2-acetylpyridine-aminoguanidine (L), are reported. The complex of the formula [Cd2Cl6(HL)2] (1) was obtained in the reaction of warm aqueous solutions of chloride salts of Cd(II), Zn(II) and the ligand, while the reaction of cadmium bromide and the ligand in the presence of deprotonating agent as well as ammonium thiocyanate resulted in the formation of the complex in which Schiff base has both the role of the ligand and the counterion, viz., [HL][Cd(HL)(NCS)2XY]·H2O (2), where X is Cl- or Br-, and Y Br- or SCN-. The complexes were characterized by IR spectroscopy, elemental analysis, conductometric measurements and single crystal X-ray diffraction. The unusual bidentate coordination of the Schiff base lead to significant changes in the geometry of this molecule (from almost planar in free form and as a tridentate ligand to twisted as a bidentate ligand). Besides, in complex 1 relatively rare bridging coordination of Cl- in octahedral Cd(II) is found, while the crystal structure of complex 2 exhibits substitutional disorder, and contains four different anions: [Cd(HL)(NCS)2Br(SCN)]- (ca. 61 %), [Cd(HL)(NCS)2Cl(SCN)]- (ca. 35 %), [Cd(HL)(NCS)2Br2]- (ca. 3 %) and [Cd(HL)(NCS)2ClBr]- (ca. 1 %).

AB  - Three novel copper complexes with tridentate N2O ligand di(2-pyridil) ketone 1-adamantoyl hydrazone (Addpy) of the formula [(Cu2Cu2I)-Cu-II(Addpy)(2)Br-2(mu-Br-4)] (1), catena-poly[CuCl(mu-Addpy)(mu-Cl)CuCl2](n) (2) and [Cu(Addpy)(NCS)(2)] (3) were synthesized. Complexes are characterized by X-ray crystallography, spectral (UV-Vis, FTIR), electrochemical (CV) analyses, and magnetochemical measurements. Investigation of anticancer potential of Cu(II) complexes, mode of cell death, apoptosis, and inhibition of angiogenesis were performed. All tested malignant cell lines (HeLa, LS174, A549, K562, and MDA-MB-231) showed high sensitivity to the examined Cu(II) complexes. It has been shown that the complexes induce apoptosis in the caspase 3-dependent manner, whereas the anti-angiogenic effects of 1, 2, and 3 have been confirmed in EA.hy926 cells using a tube formation assay.

AB  - A novel pyridoxal thiosemicarbazone (PLTSC) compound, exhibiting ligating properties, of the formula PLTSC center dot HCl center dot 2H(2)O (1) was synthesized and characterized by X-ray analysis. The PLTSC ligand 1 displays significantly different conformation in comparison to the five previously reported compounds of this type. The structural properties of six PLTSC ligands in different conformations were compared in order to establish the structural differences and understand the factors that facilitate particular conformations. The analysis indicated great structural flexibility of the PLTSC ligands. The PLTSC ligand 1 is essentially a planar molecule with the r.m.s deviation of all non-H atoms equal to 0.06 angstrom. Consequently, the molecules of 1 form a layered three-dimensional structure which is stabilized by a variety of hydrogen bonds: O-H center dot center dot center dot O, O-H center dot center dot center dot N, O-H center dot center dot center dot Cl, O-H center dot center dot center dot S, N-H center dot center dot center dot O, N-H center dot center dot center dot N, N-H center dot center dot center dot Cl, N-H center dot center dot center dot S. In addition, the crystal structure of the Fe(III) complex with the ligand 1 of the formula [Fe(PLTSC)Cl-2(H2O)]Cl was resolved by single-crystal X-ray analysis and structural properties of this octahedral complex were discussed and compared to those of uncoordinated PLTSC ligand.

AB  - The title compound, C9H13N4O3+center dot NO3-, is the first structurally characterized Schiff base derived from semicarbazide and pyridoxal. Unusually for an unsubstituted semicarbazone, the compound adopts a syn conformation, in which the carbonyl O atom is in a cis disposition relative to the azomethine N atom. This arrangement is supported by a pair of hydrogen bonds between the organic cation and the nitrate anion. The cation is essentially planar, with only a hydroxymethyl O atom deviating significantly from the mean plane of the remaining atoms (r.m.s. deviation of the remaining non-H atoms = 0.01 angstrom). The molecules are linked into flat layers by N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds. O-H center dot center dot center dot O hydrogen bonds involving the hydroxymethyl group as a donor interconnect the layers into a three-dimensional structure.

AB  - The title compound, [Cu(C9H13N5O2)(CH4O)](NO3)(2), consists of square-planar cationic complex units where the Cu-II centre is coordinated by an N, N, O-tridentate pyridoxal aminoguanidine Schiff base adduct and a methanol molecule. The tridentate ligand is a zwitterion exhibiting an almost planar conformation. The dihedral angles between the mean planes of the pyridoxal ring and the six-and five-membered chelate rings are all less than 2.0 degrees. The charge on the complex cation is neutralized by two nitrate counter-ions. Extensive N -H center dot center dot center dot O and C -H center dot center dot center dot O hydrogen bonding connects these ionic species and leads to the formation of layers. The pyridoxal hydroxy groups are the only fragments that deviate significantly from the flat layer structure; these groups are involved in O-H center dot center dot center dot O hydrogen bonding, connecting the layers into a three-dimensional crystal structure.

Also, the first complexes with the ligand coordinated in triply deprotonated monoanionic form of the formula [Cu(PLGT)N(3)] and [Co(PLGT)(NO(2))(2)NH(3)] center dot 3H(2)O are reported. The single crystal X-ray analysis of [Cu(HPLGT)(NCS)(2)] showed that Cu(II) is placed in a square-pyramidal surrounding consisting of one tridentate Schiff base and one NCS group in the basal plane and the other NCS group in the apical position. Intermolecular hydrogen bonds leading to centrosymmetrical dimerization of these complexes were discussed. In the reaction of Girard-T and Hacac in the presence of CuCl(2), a mixture of single crystal complexes of the composition [Cu(3,5-Me(2)pz)(2)Cl(2)](2) and [Cu(acac)(2)] center dot 2[Cu(3,5-Me(2)pz)(2)Cl(2)] was obtained and X-ray analysis of the latter one was reported.

AB  - The ligand, salicylaldehyde Girard-T hydrazonium chloride, [H(2)SalGT]Cl (1), and two complexes [Cu(HSalGT)X-2]center dot H2O (X = Br(2); Cl(3)) were synthesized and their crystal structures were determined by single-crystal X-ray analysis. In the two isostructural complexes, the Cu(II) is located in a square-pyramidal environment, with the chelating ligand and one halogen atom in the basal plane and the second halogen in the apical position. The most apparent structural difference between the 1 and its complexes 2 and 3 is the orientation of the N(CH3)(3) group: in 1, it is practically coplanar to the rest of the molecule, while in 2 and 3 it is oriented to the side of the axially bonded halogen, which can be explained by the C-H center dot center dot center dot X intramolecular interactions. The compounds were characterized by elemental analysis, molar conductivity, magnetic susceptibility and electronic absorption spectra.

AB  - The crystal structure of [Co-III(L)(py)(3)][(CoCl3)-Cl-II(py)] (H2L = salicylaldehyde. semicarbazone) was determined by X-ray analysis based oil two single crystal X-ray experiments performed at 120 K and 293 K. respectively. It was found that the pyridine ligand of the complex anion is disordered over two positions. The preferential position of this pyridine found at 120 K was explained in terms of the C-H...Cl intermolecular interaction between the tetrahedral [Co-II(py)Cl-3](-) anions. The mer-octahedral geometry of the cation in the presented crystal structure was compared with previously published structures of similar composition, [Co-III(L-I)(py)(3)](+)[(CoCl3)-Cl-II(py)]-.EtOH and [Co-III(L-I)(py)(3)]I-+(3)- (H2LI = salicylaldehyde S-methylisothiosemicarbazone). Although the tetrahedral [(CoCl3)-Cl-II(py)](-) anions possess the same charge, they i-mutually form different intermolecular interactions which can be realized either by C-H...Cl hydrogn bonds or by pi-pi interactions between the pyridine rings.
