Synthesis and Crystal Structure of 2—Benzoyl Pyridine Thiosemicarbazat

摘要

cqvip:The title complex, 2 benzoyl pyridine thiosemicarbazato palladium(II) chloride [C 13 H 11 N 4SPdCl, M r =379.17], crystallizes in monoclinic, space group C2/c with a=12.1061(5), b=21.877(3), c=11.4832(6), β=108.29(9)°, V=2887.7(4) 3, Z = 8, D c =1.827g/cm 3; μ= 1.608cm -1 and F(000)=1568. R =0.0281 and wR =0.0684 for 1446 reflections with I>2σ(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 β nitrogen atoms.
