Crystal structure of bis[ μ-bis(diphenylphosphino)methane]-( μ-chloro)- quinolinechlorodicopper(I) —quinoline — water (1:2:1), [Cu2(CH2(P(C6H5)2)2)2(C9H7N)Cl2] · (C9H7N)2 · H2O

Source of material Am ixture of CuCl (0.0292 g, 0.3 mmol) and bis(diphenylphosphino)methane (dppm, 0.1155 g, 0.3 mmol) in the presence of an excess of quinoline (1 ml) in acetonitrile (5 ml) was stirred at room temperature for 7h ours, then filtered. Subsequent diffusion of diethyl ether vapor into the filtrate resulted in the formation of yellow crystals of [Cu2(dppm)2(C9H7N)Cl2 ]·( C 9 H 7N)2 ·H 2O. Experimental Details Metal atom centers were located from the E-maps and other nonhydrogen atoms were located in successive difference Fourier syntheses. The final refinements were performed by full matrix least-squares methods with anisotropic thermal parameters for non-hydrogen atoms on F 2 . Two Ha toms of water were found in difference electron density maps, and refined were performed with isotropic thermal parameters. All other hydrogen atoms were located in the calculated sites and included in the final refinement in the riding model approximation with displacement parameters derived from the parent atoms to which they were bonded. Final difference Fourier maps showed the highest and lowest electron densities of 0.767 and !0.683 eA !3 ,r espectively.
