Abstract
A new thioantimonate [Mn2Sb4S8(N 2H4)2] (1) was solvothermally synthesized by reacting Mn and Sb2S3 with S in hydrazine monohydrate solution. The single crystal structure analysis revealed that all Mn sites adopt distorted octahedral shapes and all Sb sites have either four-fold coordinated SbS4 configurations or square pyramidal SbS5 geometry. These polyhedra units are interconnected into two-dimensional layers via the sharing S atoms. These layers are further bridged into a novel three-dimensional framework by intra- and inter-layer hydrazine ligands. The compound 1 is a semiconductor with a band gap of 1.59 eV and displays paramagnetic behavior at high temperature and switches to antiferromagnetic ordering at 40 K.
