Synthesis and properties of the chain‐like polymeric copper (II) complexes bridged by bis(diphenylphosphino oxide) ethane

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.
