Abstract
The synthesis and characterization of copper(I) complexes containing bisphosphines such as bis(2-diphenylphosphinoimidazol-1-yl)methane (1), bis(5-diphenylphosphinopyrazol-1-yl)methane (2) and bis(5-diphenylphosphino-1,2,4-triazol-1-yl)methane (3) is reported. Bisphosphines 1–3 exhibit bidentate (κ2P,P) chelating mode of coordination. The crystal structures of 4–6 have been established by single crystal X-ray crystallography. Luminescence spectra of complexes 7–9 recorded at room temperature in dichloromethane solution displayed single emission bands at 541, 542 and 519nm, respectively, with moderate quantum yields.
