Abstract

Abstract Thioantimonates, Solvothermal Synthesis, Chalcogenides The reaction of elemental manganese, antimony and sulfur with ethylamine under mild solvothermal conditions yielded a thioantimonate(III) with composition Mn2(EA)2Sb2S5 (EA = C2H5NH2) that is a new member of a series of polymeric manganese thioantimo-nates(III). The structure of the title compound consists of layers of a neutral mesh-like Mn2Sb2S5 framework. The ethylamino ligands coordinated to the Mn centres separate the sheets and fill the voids within the layers formed by the interconnection of Mn2Sb2S4 hetero-cubane like building blocks. Below 273 K a reversible phase transition occurs, which is accom­panied by a doubling of the crystallographic a-axis.
