چکیده

The asymmetric unit of the title compound, C(6)H(7)N(2)O(2) (+)·Cl(-)·0.5H(2)O, consists of two protonated 2-amino-3-carb-oxy-pyridine cations, two chloride anions and one mol-ecule of water. The crystal packing can be described as alternating layers of cations and anions parallel to (110), which are linked together by O(w)-H⋯Cl inter-actions. In the crystal, four types of classical hydrogen bonds are observed, viz. cation-anion (O-H⋯Cl and N-H⋯Cl), cation-cation (N-H⋯O), cation-water (N-H⋯O(w)) and water-anion (O(w)-H⋯Cl), resulting in the formation of an infinite three-dimensional network.

The title complex, [ZnCl(2)(C(12)H(18)N(2)O)]·0.5H(2)O, is a mononuclear zinc(II) compound derived from the zwitterionic form of the Schiff base 2-[3-(dimethyl-amino)propyl-imino-meth-yl]-phenol. The Zn(II) atom is four-coordinated by the imine N and the phenolate O atoms of the Schiff base ligand, and by two chloride ions, in a distorted tetra-hedral coordination geometry. The dimethyl-ammonio...
