Abstract

Reaction of 4-pyridincarbohydrazide, 2-chlorobenzaldehyde and Cd(II) ion in ethanol resulted the complex trans -[Cd(H 2 O) 4 (C 13 H 10 N 3 ClO) 2 ](NO 3 ) 2 . The title complex was characte-rized by elemental analyses, UV-Vis and IR spectroscopy. The structure of complex also was established by single crystal X-ray diffraction analysis. The [Cd(H 2 O) 4 (C 13 H 10 N 3 ClO) 2 ](NO 3 ) 2 complex has monomeric structure with monoclinic crystal system and space group of P2 1 /n , a = 7.7720(16) A, b = 17.594(4) A, c = 11.823(2) A, β = 97.29(3)° with Z = 2. The cadmium atom in the crystal structure has octahedral geometry by coordination of the two nitrogen atoms of ligand and four oxygen atoms of water molecules.
