Abstract:

Compound [InAsS4(2,2′-bipy)]2, which contains AsS3-4(As(Ⅲ)) unit, was synthesized by the hydrothermal method. The compound crystalizes in monoclinic space group P21/c with a=0.89799(9) nm, b=2.1794(2) nm, c=1.43736(14) nm, β=91.274(2)°, V=2.8123(5) nm3. In this compound, the AsS3-4(As(Ⅲ)) unitis stabilized by metal-amino complex [In(2,2′-bipy)]3+. The effect of metal charge on the formation of this product was discussed and the band gap of the as-synthesized semiconductor is found to be 1.35 eV.

Key words: metal arsenic sulphides, metal-amino complexes, hydrothermal synthesis
