Three heteronuclear complexes were synthesized and characterized: [Cu (oxpn) Zn (bpy) _2] (ClO_4) _2 · 1 / 2H_2O (1), [Cu (oxpn) Zn- (phen) _2] (ClO_4) _2 · 2H 2 O (2) [Cu (oxpn) Zn (NO 2 -phen) 2] (ClO 4) 2 · 2H 2 O (3) [bpy = 2,2’-bipyridyl, phen = -phen = 5-nitro-1,10-phenanthroline oxpn = N, N’-bis (3-aminopropyl) oxalate anion] .2 The crystals are monoclinic, P2 / n space group , B = 1.2924 (3), c = 2.2802 (3) nm, β = 108.42 (2) °, V = 4.1869 nm ~ 3, Z = 4 and Dm = 1.409 g /cm~3,μ=12.812cm~(-1),F(000)=1812, the final deviation factor R = 0.093, R_w = 0.099. The structural analysis confirmed that the complexes have an extended oxalamide bridge structure, Cu (Ⅱ) and Zn (Ⅱ) are planar tetragonal and distorted octahedron, respectively, and the symmetry of the cation is approximately C 2v. In addition, the electronic spectra of the complexes were also assigned and the correlations between EPR , Effective magnetic moment and other data were discussed.
