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  - The complex formation of 3,5-dimethylpyrazole-1-carboxamidinium nitrate, HL center dot HNO(3) with ammine complexes of cadmium(II) halides (Cl, Br, I) and zinc(II) chloride has been investigated under self-controlled reaction conditions. The complexes have been characterized by X-ray diffraction, FT-IR spectroscopy, thermal analysis and quantum chemical calculations. In the case of cadmium bromide and iodide salts, isostructural complexes with composition of [CdX(2)(HL)(2)] were formed. With CdCl(2) a binuclear octahedral [Cd(2)(HL)(4)(mu-Cl)(2)](NO(3))(2) complex is obtained. Zinc(II) chloride with HL center dot HNO(3) gives [Zn(HL)(2)Cl]NO(3), the zinc center exhibiting severely distorted five-coordinate stereochemistry, intermediate between an ideal trigonal bipyramid and a square pyramid. The course of complex formation as well as the thermal properties of the compounds has been explained using the HSAB principle. The assignment of the FT-IR spectra was supported by DFT computations.
