Cu(CTHsO3)2(C6H7NO)2), Mr = 556.03, monoclinic, C2/c, a = 15.786 (1), b = 13.299 (2), c = 12.083 (1) A, /3 = 97.22 (1) °, V = 2516.73 A 3, Z = 4, Om = 1.45, Dx = 1.46 g cm-3, A(Cu Ka) = 1.54178/~, /z = 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 sym- metry, 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)A) and one carboxylate oxygen from each of two salicylate anions (Cu--O = 1.981 (2) A). The remaining axial positions are occupied by methanol oxygen atoms of two 2-pyri-
