摘要

At room temperature, the chain-like polymeric copper(Ⅱ)complexes bridged by bis(diphenylphosphino oxide) ethane (dppeO2), [Cu(dppeO2)X2]n[X= Cl(1), Br(2)] have been prepared and characterized by elemental analysis, 31P NMR,TG-DTA X-ray analysis for [CuBr2(dppeO2)]n. The chain is composed of subunits 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(Mo Kα), a=1.2286(2) mm, b =2.0555(8) nm, c = 1.0652(2) nm, β=97.366(9)°, V=2.668 nm3, Z=4, Dcalc=1.628g.cm-3,R =0.066; Rw= 0.091.
