STRUCTURE OF COPPER(II) SALICYLATES - BIS(3-PYRIDYLMETHANOL)BIS(SALICYLATO)COPPER(II)

[CU(C7H5O3)2(C6H7NO)2], M(r) = 556.03, orthorhombic, Pbca, a = 12.947 (1), b = 9.401 (3), c = 20.005 (3) angstrom, V = 2435.16 angstrom3, Z = 4, D(m) = 1. 50, D(x) = 1.52g cm-3, lambda(Cu Kalpha) = 1.54178 angstrom, mu = 16.949 cm-1, F(000) = 1148, T = 293 K, final R = 0.044 for 1 122 observed reflections. The crystal structure consists of molecules bonded together into layers parallel to (100). The coordination polyhedron of Cu(II) is a distorted octahedron built up by four short bonds in the equatorial plane [two Cu-N and two Cu-O bonds with bond lengths 1.944 (4) and 2.029 (4) angstrom] and two longer apical Cu-O bonds [2.622 (4) angstrom]. The 0 atoms forming apical bonds belong to the different molecules of 3-pyridylmethanol.
