Abstract

The antimony(III) chloride complexes with 2- and 4-benzylpyridine were synthesized and studied using elemental analysis, X-ray diffraction analysis, IR spectroscopy, and luminescence spectroscopy. The crystal structure of bis(2-benzylpyridinium) pentachloroantimonate(III) was determined. The crystals are triclinic: a = 9.628(1) Å, b = 15.284(2) Å, c = 19.174(2) Å, α = 99.962(2)°, β = 101.233(2)°, γ = 99. 216(2)°; Z = 4, ρ(calcd) = 1.591 g/cm3, space group P $$\overline 1$$ , R = 0.0358. The structure consists of polymeric chains of [Sb2Cl10]4n– n anions and [C12H11NH]+ cations combined into a framework by the N–H···Cl hydrogen bonds. The electronic and geometrical factors responsible for a relatively low intensity of the luminescence emitted by the complexes of antimony(III) chloride with 2- and 4-benzylpyridine at 77 K are discussed.
