Abstract
Using an organoamine, 2,5-bis (1-imidazoly) pyridine (L), a novel inorganic-organic hybrid material based on antimony halide formulated as {(CH3)2L}2+{(Sb4Cl8I8)0.5}2–(1) was synthesized in situ via solvothermal technique and characterized by the single-crystal X-ray diffraction. During the synthesis, the organoamine L was transformed in situ into the imidazolium ion, {(CH3)2L}2+. In the compound 1, four Sb(III) ions are linked by two \({u_{{3^ - }}}\)I– and four u\({u_{{2^ - }}}\)I– ligands into a (Sb4I8Cl8)4–unit, in which eight Cl–ions and two I–ions act as the terminal ligands. The uncoordinated {(CH3)2L}2+ organoamine moieties are linked with the (Sb4I8Cl8)4– clusters via H bonds into three-dimensional (3D) supramolecular architecture. The band structure calculation shows that the compound has an indirect band gap of 2.253 eV.
