Abstract
A new thioantimonate(III) with the 2D anionic framework, [3-depnH2]Sb8S13·H2O 1 (3-depn = 3-dimethylpropanediamine), has been synthesized under solvothermal reactions and characterized by single-crystal X-ray diffraction analysis, IR, elemental analysis, EDS, and X-ray powder diffraction. In the 2D porous (Sb8S132-)n layer of compound 1, there are two different coordination modes for Sb atoms. 1 is a semiconductor with the band gap of Eg = 1.97 eV (629 nm). The thermogravimetric analysis is also discussed. Moreover, the impedance spectroscopic measurements of 1 reveal that the bulk conductivity is 5.68 Ã 10â6 S cmâ1, and the grain boundary conductivity is 1.43 Ã 10â6 S cm â1.
