Synthesis and crystal structure of 2-benzoyl pyridine thiosemicarbazato palladium(II) chloride

The title complex, 2-benzoyl pyridine thiosemicarbazato palladium(II) chlor ide [C13H11N4SPdCl, M-r = 379. 17], crystallizes in monoclinic, space group C2/c with a = 12.1061 (5), b = 21.877(3), c = 11.4832(6) Angstrom, beta = 108.29(9)degrees, V = 2887.7(4) Angstrom3, Z = 8, D-c 1.827g/cm(3); mu = 1. 608cm(-1) and F(000) = 1568. R = 0.0281 and wR = 0.0684 for 1446 reflection s with I > 2 sigma (I). X-ray crystal structure analysis revealed that the coordination geometry of Pd atom is a distorted square plane with two Pd - N bonds, one Pd - S bond and one Pd - Cl bond. The Schiff-base ligand loses a proton from its tautomeric thiol form and coordinates to the Pd atom via the mercapto sulfur and the beta -nitrogen atoms.
