STRUCTURE OF BIS(SALICYLATO)BIS(2-PYRIDYLMETHANOL)COPPER(II)

[Cu(C7H5O3)2(C6H7NO)2], M(r) = 556.03, monoclinic, C2/c, a = 15.786 (1), b = 13.299 (2), c = 12.083 (1) angstrom, beta = 97.22 (1)-degrees, V = 2516.73 angstrom 3, Z = 4, D(m) = 1.45, D(x) = 1.46 g cm-3, lambda(Cu K-alpha) = 1.54178 angstrom, mu = 16.389 cm-1, F(000) = 1148, T = 293 K, final R = 0.046 for 1300 observed reflections. The copper(II) atom is situated on a centre of symmetry, and has distorted octahedral coordination. It is bonded in a trans square-planar arrangement to the nitrogen atoms of two 2-pyridylmethanols [Cu-N = 1.981 (1) angstrom] and one carboxylate oxygen from each of two salicylate anions [Cu-O = 1.981 (2) angstrom]. The remaining axial positions are occupied by methanol oxygen atoms of two 2-pyridylmethanol ligands [Cu-O = 2.331 (1) angstrom].
