摘要

Abstract

The reactions of SbI₃ with iodides of cations of the pyridinium family in a mixture of acetonitrile and acetone afford two polymeric iodoantimonate complexes: (1-MePy){[SbI₄]} (I) and (3-Br-1-MePy){[SbI₄]} (II). Specific features of the crystal structures are determined by X-ray diffraction (XRD). The thermal stability of compounds I and II is evaluated by thermogravimetry. The optical forbidden bandgaps are estimated from the diffuse reflectance spectra.
