STRUCTURE OF CATENA-(ACETATO)(DI-2-PYRIDYLAMINE)-MU-NITRATO-COPPER(II)

[Cu(NO3)(C2H3O2)(C10H9N3)], M(r) = 355.79, monoclinic, P2(1)/n, Z = 4, a = 12.859 (3), b = 9.674 (2), c = 12.247 (3) angstrom, beta = 113.52 (2)degrees, V = 1396.93 angstrom 3, D(m) (flotation) = 1.720 (6), D(x) = 1.692 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 15.36 cm-1, T = 298 K, F(000) = 724, 1822 unique observed reflections. R = 0.037. The local molecular CuN2O2O2' chromophore involves an elongated rhombic octahedral structure, with nearly symmetrically bonded di-2-pyridylamine (dpyam) and bidentate acetate groups bonding in the plane and bridging 'semi-coordinate' nitrate groups completing the six coordination.
