摘　　要：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.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.
