The First Example of Solvothermally Synthesized Thioantimonates(V) with Ethylenediamine Coordinated Lanthanide(III):  [Sm(en)4]SbS4·0.5en and [Sm(en)3(H2O)(μ-SbS4)]

Under mild solvothermal conditions two novel thioantimonates(V) [Sm(en)4]SbS4·0.5en (1) and [Sm(en)3(H2O)(μ-SbS4)] (2) were synthesized; the structure of 1 contains discrete [Sm(en)4]3+ and [SbS4]3- ions, while 2 consists of neutral [Sm(en)3(H2O) (μ-SbS4)] one-dimensional chains.
