At room temperature, the chain-like polymeric copper (II) complexes bridged by bis (diphenylphosphino oxide) ethane (dppeO2), [Cu(dppeO2)X2]n[XCI(1), Br(2)] have been prepared and characterized by elemental analysis, 31P NMR, TG-DTA and X-ray analysis for [ CuBr2 ( dppeO2) ]n. The chain is composed of submits containing tetrahedron coordinated copper (II) atoms. The four-coordinated copper(II) atom is ligated to another four-coordinated copper(II) atom through dppeO2. The coordination sphere of copper (II) atom is completed by two monodentate bromide and two oxygen atoms from bridging dppeO2. Crystal data are as follows: C26-H24CuP2Br2O2, 0.50 mm × 0.40 mm × 0.40 mm, monoclinic, space group: C2/c, λ = 0.07107 nm(Mo Kα), a= 1.2286(2) nm, b=2.0555(8) nm, c = 1.0652(2) nm, β=97.366(9)°, V = 2.668nm3 Z = 4, Dcalc =1.628 g·cm?3, R=0.066; Rw = 0.091.
The mononuclear copper(I) complex, [Cu(dppe)2](PF6)(CH3COCH3) [dppe = bis-(diphenylphosphino)ethane] has been synthesized and characterized by X-ray crystallography. The crystal belongs to monoclinic, Mr=1062.3, space group P21/n with cell parameters a =14.741(2), b =19.354(8), c =18.587(3) ? = 91.41(1)°, V = 5301.5 3, Z = 4, Dc=1.302 g/cm3, F(000)= 2200, = 6.16cm-1, R=0.062, Rw = 0.068. A total of 9679 independent reflections were collected, of which 4574 reflections with I >3σ(I) were observed. The central Cu atom is coordinated by four P atoms from dppe to form a distorted tetrahedral environment. In the coordination sphere the bond lengths of CuP(1), CuP(2), CuP(3) and CuP(4) are 2.298(2), 2.305(2), 2.311(2) and 2.295? respectively; and the PCuP bond angles vary from 87.52(9) to 120.12(9)?

The novel trinuelear copper(I) complex [Cu3(μ3-Br)2(dppm)3]Br has been obtained by reaction of bis(diphenyl-phosphino)methane (dppm) with cupric bromide. The title complex was characterized by single-crystal X-ray analysis, elemental analysis, molecular weight determination, 31P NMR and its conductivity was also measured. The [Cu3(dppm)3Br2] + cation consists of a triangular array of copper atoms, with dppm ligands (Ph2PCH2PPh2) bridging each edge of the triangle and two triply bridging Br groups bound to the two faces of the Cu3 unit.
