摘要:
The oxpn ligand [oxpn = N, N'-bis(3- aminopropyl)oxamide] in the title compound, mu-[N,N'-bis(3-aminopropyl)oxamidato(2-)]-N,N',O':N ",N''',O-bis[(imidazole N-3)(nitrato-O)copper(II)], [Cu-2(C8H16N4O2)(NO3)(2)(C3H4N2)(2)], is bis-tridentate in a trans conformation, bridging two Cu-II ions to form a centrosymmetric binuclear molecule. The symmetry-equivalent central Cu-II ions are located in a distorted square-based pyramid, with an O atom from the nitrate ion bonded at the axial site, and a Cu ... Cu distance of 5.242 (2) Angstrom.
