At room temperature, the chain‐like polymeric copper (II) complexes bridged by bis (diphenylphosphino oxide) ethane (dppeO 2 ), [Cu(dppeO 2 )X 2 ] n [XCI(1), Br(2)] have been prepared and characterized by elemental analysis, 31 P NMR, TG‐DTA and X‐ray analysis for [ CuBr 2 ( dppeO 2 ) ] 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 dppeO 2 . The coordination sphere of copper (II) atom is completed by two monodentate bromide and two oxygen atoms from bridging dppeO 2 . Crystal data are as follows: C 26 ‐H 24 CuP 2 Br 2 O 2 , 0.50 mm × 0.40 mm × 0.40 mm, monoclinic, space group: C 2 /c, λ = 0.07107 nm(Mo K α ), a= 1.2286(2) nm, b =2.0555(8) nm, c = 1.0652(2) nm, β=97.366(9)°, V = 2.668nm 3 Z = 4, D calc =1.628 g·cm −3 , R =0.066; R w = 0.091.
