Synthesis, crystal structures of [M(tepa)] 2(μ 2-Sn 2Se 6)(M = Fe and Co), showing a selenidostannate bridge for transition metal complex cations

Two selenidostannates were prepared by solvothermal reaction. The Sn 2 Se 6 4 - anion as an bridging ligand connects two transition metal complex cations to form neutral centrosymmetric [M(tepa)] 2(μ 2-Sn 2Se 6) compounds (M = Fe 2+ and Co 2+).

Description
Summary:Two selenidostannates were prepared by solvothermal reaction. The Sn 2 Se 6 4 - anion as an bridging ligand connects two transition metal complex cations to form neutral centrosymmetric [M(tepa)] 2(μ 2-Sn 2Se 6) compounds (M = Fe 2+ and Co 2+). Two new selenidostannates [M(tepa)] 2(μ 2-Sn 2Se 6) (tepa = tetraethylenepentamine, M = Fe 2+ 1 and Co 2+ 2) were prepared by solvothermal reaction at 157 °C. Compounds 1 and 2 are isostructural. The M 2+ ion has a distorted octahedral geometry comprised of five N atoms from tepa ligands and one terminal Se atom of the Sn 2 Se 6 4 - anion. As a bridging ligand, Sn 2 Se 6 4 - anion connects two transition metal complex cations by trans terminal Se atoms to form neutral centrosymmetric [M(tepa)] 2(μ 2-Sn 2Se 6) moieties. Their thermal and optical properties were studied.
