Abstract

A new thioantimonate [Mn₂Sb₄S₈(N₂H₄)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. © 2011 Elsevier B.V.
