• Crystal structure

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 [(SbS3)-S-III](3-) and a [(SbS4)-S-V](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 lambda delta-lambda lambda-conformation and the other the delta lambda-lambda delta-conformation. Several intermolecular S center dot center dot center dot H-N bonding interactions are found between the cations and the anions.
