The title complex [Cu2(μ-dppm)2(μ-Et2dtc)](ClO4)@EtOH@0.25H2O (dppm = bis-(diphenylphosphino)methane, Et2dtc = diethyldithiocarbamate) has been synthesized and characterized by single-crystal X-ray diffraction analysis. The crystal structure is of monoclinic,space group C2/c with a = 42.587(1), b = 14.1653(4), c = 20.5649(5)(A),β = 105.945(1)°, V = 11928.6 (A)3, C57H60.5ClCu2NO5.25P4S2, Mr = 1194.09, Z = 8, Dc = 1.330 g/cm3, μ(MoKα) = 0.98 mm-1 and F(000) = 4948. A total of 15243 reflections were collected, of which 7322 were unique.The structure was refined to R = 0.0739 and wR = 0.1846 for 5135 observed reflections with Ⅰ＞2σ(Ⅰ). The crystal structure consists of the complex cation [Cu2(μ-dppm)2(u-Et2dtc)]+, anion ClO4-and solvate H2O and EtOH, where the dinuclear Cu( Ⅰ ) atoms are bridged doubly by two dppm ligands and singly by Et2dtc to give three five-membered rings. The Cu(Ⅰ) atom is in an approxi mately trigonal-planar environment with the P2S chromophore. The short Cu…Cu separation (2.7111 A) suggests the presence of metal-metal contact.
