STRUCTURE OF [1-(3,5-DIMETHYL-1-PYRAZOLYL)-3-THIAPENTANE-N,S]-BIS(NITRATO-0,0)COPPER(II)

[Cu(C9H16N2S)(NO3)2], M(r) = 371.9, orthorhombic, Pca2(1), a = 11.55 (1), b = 7.877 (2), c = 16.866 (5) angstrom, V = 1534 angstrom 3, Z = 4, D(x) = 1.6 g cm-3, lambda(Mo K-alpha) = 0.71073 angstrom, mu = 16 cm-1, F(000) = 764, T = 298 K, R = 0.026 and wR = 0.040 for 1507 observed reflections [I > 2-sigma(I)]. The structure of this compound consists of a copper(II) ion coordinated by one pyrazole nitrogen [1.943 (4) angstrom], one thioether sulfur [2.332 (1) angstrom] and two monodentate nitrate anions [1.979 (4) and 2.021 (3) angstrom]. The basic coordination geometry is square planar with the nitrates in cis positions. The orientation of the nitrates results in semi coordination of two additional nitrate oxygen atoms at 2.411 (4) and 2.479 (4) angstrom. The so-defined coordination geometry is a severely distorted octahedron.
