Abstract

The new compound {Mn(dien)2}2[MnSb2S7] (dien = diethylenetriamine) was obtained under solvothermal conditions and crystallizes in the orthorhombic space group Pbca. The main structural motif is the [MnSb2S7]4– anion being constructed by a [MnS4]6– tetrahedron, a [SbIIIS3]3– and a [SbVS4]3– anion. Each thioantimonate anion shares one edge with the Mn2+ centered cation generating the [MnSb2S7]4– unit. The two independent Mn2+ cations in the two {Mn(dien)2}2+ complexes are in a distorted octahedral environment of two tridentate acting dien molecules. One cation displays the λδλλ-conformation and the other the δλλδ-conformation. Several intermolecular S···H—N bonding interactions are found between the cations and the anions.
