Novel lanthanoid thioantimonates: the first coexistence of different types of thioantimonate anions in the same framework

Abstract

Two novel lanthanoid thioantimonates [Sm4(tepa)4(μ-η23-Sb3S7)2(μ-Sb2S4)] (1, tepa = tetraethylenepentamine) and [Eu2(tepa)2(μ-SbS3)(μ-OH)]2(SbS4)(OH)·H2O (2) were solvothermally synthesized. Compound 1 represents the only example of different types of [Sb3S7]5− and [Sb2S4]2− anions coexisting in the same lanthanoid thioantimonate framework, while 2 displays rare mixed-valent Sb3+/Sb5+ character with the Sb3+ in a noncondensed pyramid [SbIIIS3]3−. The theoretical band structure and luminescence properties have also been investigated.
