Abstract

Two coordination octahedral Sn(IV) complexes [Sn(L)2] and cis-[SnCl2(L)(dmso)], where H2L is 2-hydroxyacetophenone (S-benzydithiocarbazate), were prepared and characterized by elemental analysis, IR, NMR (1H, 13C), 119Sn Mössbauer spectroscopies and X-ray diffraction techniques to investigate their structural properties. Both crystallize in the Monoclinic system, with parameters: a = 8.1905(3), b = 30.8811(15), c = 12.8959(7) Å, β = 94.465(3)° and Z = 4 for [Sn(L)2] and a = 8.5247(2), b = 21.5445(7), c = 12.3706(3) Å, β = 96.932(2)° and Z = 4 for cis-[SnCl2(L)(dmso)]. In both complexes, the Sn(IV) central atom is coordinated in a distorted octahedral geometry with the thiolate ligand (L2−) coordinated via O, N and S atoms. The 119Sn Mössbauer spectroscopy of the complexes were studied and the results revealed that both complexes posses isomer shift (δ) and quadrupole splitting (Δ), which are almost the same.
