【 摘 要 】

The reaction of KSeCOAr with InCl₃ and [MCl(PR₃)₂] in benzene afforded bimetallic complexes, [(R₃P)₂MIn(SeCOAr)₄] (PR₃ = PEt₃ or PPh₃; M = Cu or Ag; Ar = â€�?�C₆H₅ (phenyl) or 4-MeC₆H₄ (tolyl)). The triethylphosphine complexes decomposed rapidly when M = Ag while slowly when M = Cu. All these complexes were characterized by elemental analysis, IR, UV-VIS, NMR (¹H, ³¹P) spectral data. Pyrolysis in a furnace at 300°C gave tetragonal MInSe₂ (M = Cu, Ag) structure. Solvothermal decomposition of [(PPh₃)₂CuIn(SeCOAr)₄] in boiling ethylene glycol gave nanorods of CuInSe₂ which were characterized by XRD, EDAX, SEM and TEM.
