Abstract:
[Cu(C16H18N3O2)]Br.CH4O, Mr = 459.83, orthorhombic, P2(1)2(1)2(1), a = 10.452 (4), b = 12.197 (7), c = 14.984 (6) A, V = 1910 (3) A3, Z = 4, Dm = 1.61 (1), Dx = 1.599 g cm-3, lambda(Mo K alpha) = 0.71073 A, mu = 32.37 cm-1, F(000) = 932, T = 174 K, R = 0.0396, wR = 0.0419, 1146 observed reflections [I greater than 3 sigma(I)]. The title compound is a polymeric species in the solid state, with a unit cell consisting of two segments of one-dimensional chains. The ligand, a derivative of gamma-aminobutyric acid in which the amino group is substituted with two 2-pyridylmethyl moieties, coordinates to one copper atom through the three nitrogen atoms and to another copper atom through the two carboxylate oxygen atoms. The copper(II) atom has a pseudo square-pyramidal geometry, distorted by a distant sixth interaction to a carboxylate oxygen atom [Cu-O(2), 2.770 (7) A].
