Synthesis, structure and photo-luminescence of Cu[(PPh3)2](acac) (PPh3 = triphenylphosphine, acac = acetylacetone)

A novel complex Cu(PPh3)(2)(acac) 1 (PPh3 = triphenylphosphine, acac = acetylacetone) was obtained by a solution reaction and structurally characterized by X-ray diffraction. The crystal belongs to monoclinic, space group P2(1)/n with a = 13.7361(8), b = 12.8204(7), c = 19.7638(13) angstrom, beta = 95.946(2)degrees, C41H37CuO2P2, M-r = 687.19, V = 3461.7(4) angstrom(3), Z = 4, D, = 1.319 g/cm(3), S = 1.067, mu(MoK alpha) = 0.758 mm(-1), F(000) = 1432, R = 0.0403 and wR = 0.0990. Complex 1 is characterized by an isolated structure. X-ray structure analysis of 1 shows that acac behaves as a chelating ligand and PPh3 coordinates as a monodentate ligand to the Cu(I) atoms. Photoluminescent investigation reveals that the title complex displays a strong green-light emission.
