One-Dimensional Vanadium(III) Chalcogenidostannates Incorporating [V(tepa)]3+ Complexes as Bridging Groups.

Two new one-dimensional (1D) vanadium(III) chalcogenidostannates, [H2tepa]0.5n[VIII(tepa)(μ-Sn2Q6)]n [Q = S (1), Se (2); tepa = tetraethylenepentamine], were achieved by solvothermal methods, which offer the first examples of organic hybrid polymeric chalcogenidostannates incorporating [V(tepa)]3+ complexes as bridging groups. Both 1 and 2 feature the 1D sinusoidal chains of [VIII(tepa)(μ-Sn2Q6)]n containing two types of novel bridging modes of the [μ-Sn2Q6]4- anion. Their magnetic, photocurrent response, and optical properties are also studied.
