摘要:

Two novel silver(I) complexes inverted right perpendicular Ag(DPEphos)(dppe)] ClO4 (1) and [Ag(DPEphos)( dppe)] SCN (2) (DPEphos = bis[2-(diphenylphosphino) phenyl] ether, dppe = bis(diphenylphosphino) ethane) are synthesized and characterized by IR, H-1/P-31 NMR spectroscopy and fluorescence spectra. Complex 1 crystallizes in monoclinic, space group P2(1)/c with a = 14.8821(12), b = 12.6620(11), c = 36.025(3) angstrom, beta = 112.633(2)degrees, V = 6265.7(9) angstrom(3), C62H52ClO5P4Ag, M-r = 1144.24, Z = 4, D-c = 1.213 g/cm(3), F(000) = 2352, mu = 0.510 mm(-1), the final R = 0.0616 and wR = 0.1192 for 4003 observed reflections (I > 2 sigma(I)). Complex 2 crystallizes in monoclinic, space group P2(1)/c with a = 14.9021(13), b = 12.6100(11), c = 35.920(3) angstrom, beta = 112.852(2)degrees, V = 6220.2(9) angstrom(3), C63H52NOP4SAg, M-r = 1102.87, Z = 4, D-c = 1.178 g/cm(3), F(000) = 2272, mu = 0.498 mm(-1), the final R = 0.0912 and wR = 0.1706 for 3287 observed reflections (I > 2 sigma(I)). In mono-nuclear complexes 1 and 2, the Ag(I) atom is chelated by DPEphos and dppe ligand. In the P-31 NMR spectra, there are splitting signals (doublets or triplets) which can be attributed to the coupling of the Ag-107,Ag-109-P-31 (from DPEphos or dppe ligand). All the emission peaks of these complexes are attributed to ligand-centered (pi-pi*) transitions.
