Abstract
The atomic structure of antimony(III) bromide crystals with anilinium was determined by X-ray diffraction analysis of (С6H5NH3)2SbBr5 (a = 19.704(3) Å, b = 7.914(1) Å, c = 25.556(4) Å; space group Pbca, Z = 8, ρcalc = 2.365 g/cm3). The crystal structure consists of infinite chains of [SbBr5]2- complex anions formed by sharing six vertices and the anilinium (С6H5NH3)+ cations, through which the chains are linked in layers by N-H…Br hydrogen bonds. The geometrical aspects that determine the luminescent spectral properties of the complex are discussed.
