STRUCTURE OF THE DINUCLEAR COPPER(II) COMPOUND OF N,N,N',N'-TETRAKIS[2-(3,5-DIMETHYL-1-PYRAZOLYL)ETHYL]-1,2-ETHYLENEDIAMINE (TPED), [CU2(TPED)(H2O)2(NO3)2](NO3)2.2CH3OH

Mu-(N,N,N',N'-tetrakis[2-(3,5-dimethyl-1-pyrazolyl)ethyl]-1,2-ethylenediamine}-bis[aquanitra-tocopper(II)] dinitrate dimethanol solvate, asymmetric unit [Cu(C30H48N10)0.5(H2O)(NO3)]NO3.CH3OH, M(r) = 512.0, monoclinic, P2(1)/n, a = 12.683 (4), b = 10.374 (2), c = 19.229 (4) angstrom, beta = 111.92 (2)-degrees, V = 2347.0 angstrom3, Z = 4, D(x) = 1.44 g cm-3, lambda(Mo Kalpha) = 0.710730 angstrom, mu = 9.77 cm-1, F(000) = 1072, T = 298 K; the structure was solved by the heavy-atom method and refined by least squares to a residual R of 0.036 (wR = 0.052) for 2361 significant [I > 2sigma(I)] reflections. The Cu(II) ion is surrounded by two pyrazole N atoms at 1.993 (4) and 2.013 (3) angstrom, one amine N atom of tped at 2.303 (3) angstrom, an O atom of one of the nitrate anions at 2.063 (3) angstrom, and a water O atom at 1.947 (3) angstrom in a distorted square pyramid. The ligand accommodates two Cu(II) ions at a distance of 6.563 (1) angstrom. A hydrogen-bond network connects the methanol molecule to the coordinated nitrate ion, and the coordinated water molecule to the methanol molecule and to the non-coordinated nitrate ion. In this way the asymmetric units are linked together in zigzag chains in a plane perpendicular to the b axis.
