AB  - The asymmetric unit of the title compound, (C12H18N3O4)(2)[ZnCl4]center dot CH3OH, consists of two Girard reagent-based cations, a tetrachloridozincate anion and a molecule of methanol as solvate. These components are interconnected in the crystal structure by an extensive network of O-H center dot center dot center dot O, N-H center dot center dot center dot O, C-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, N-H center dot center dot center dot Cl and C-H center dot center dot center dot Cl hydrogen bonds. The shortest intermolecular interaction is realized between the cation and anion [H center dot center dot center dot Cl = 2.29 (5) angstrom; O-H center dot center dot center dot Cl = 167 (3)degrees]. C-H center dot center dot center dot O interactions also play a important role in the interconnection of the cations.

AB  - A double zwitterionic Schiff base was synthesized using the amino acid L-histidine and o-vanillin (2-hydroxy-3-methoxy benzaldehyde). Both the phenol and carboxyl groups are deprotonated, and the imine nitrogen atom and histidine-imidazole ring are protonated to give the double zwitterion with an intramolecular (imine)N-H(+)center dot center dot center dot(-)O(phenol) hydrogen bond (ketoamine form). Such a ketoamine form in a double zwitterion is assumed in the catalytic cycle of enzymatic transformations of amino acids with the cofactor (vitamin B6) pyridoxal-5-phosphate (PLP). A high-resolution, low-temperature, single-crystal X-ray diffraction data set on N-o-vanillylidene-l-histidine (also named 3-methoxysalicylidene-l-histidine or N-(2-oxy-3-methoxy-benzylidene)-L-histidine, OVHIS) is used in the analysis of molecular electrostatic properties and intermolecular interactions. All oxygen atoms in the molecule (four in total) are mutually almost coplanar and located (externally) on the same side of molecule. These four O atoms carry significant negative charge and form a large area of strong negative electrostatic potential (appropriate for bonding to a metal atom). The protonated and, thus, positively charged imidazole ring is situated on the opposite side of the molecule from the area of the O atoms. Consequently, the OVHIS molecule is highly polarized and has a very high molecular dipole moment of 42.4 D in the solid state (calculated from experimental X-ray data). Two strong intermolecular charge-assisted N-H(+)center dot center dot center dot(-)O hydrogen bonds (with H center dot center dot center dot O distances of 1.61 angstrom) together with other D-H center dot center dot center dot O interactions (D = N, C) contribute to a large molecular dipole enhancement which occurs upon crystallization. The topologies of the bonding within the molecule as well as its hydrogen bonds have been investigated according to Baders quantum theory of atoms in molecules (QTAIM). (1)H solid-state magic angle spinning nuclear magnetic resonance (MAS NMR) was used to confirm the zwitterionic structure in the solid state.

AB  - The title compound, [Ni(C28H30N3O2PS)], crystallizes with two independent molecules in the asymmetric unit. The Ni-II atoms are in significantly deformed square-planar environments formed by an ONNP donor set from a thiosemicarbazide-based tetradentate ligand. The Ni-II atom and the ONN donor atoms are nearly coplanar, while the P atom deviates from their mean planes by 0.278 (4) and 0.202 (4) angstrom for the two independent molecules. The P-containing chelate rings are remarkably non-planar, adopting a boat conformation, which is unusual for chelate rings in transition metal complexes with thiosemicarbazide-based tetradentate ligands. The orientation of the ethoxy group bonded to this chelate ring is caused by an intramolecular C-H center dot center dot center dot pi interaction with the opposing phenyl ring. There are no hydrogen bonds; instead, numerous intermolecular C-H center dot center dot center dot pi interactions dominate in the crystal packing.
