Abstract
Two types of assembly with the same carboxylate ligands, [Cu-II{OCO-2, 6-(CH3CONH)(2)C6H3}2(H2O)2] . nH(2)O (n = 1 (1), 4 (2)), and a common monomer unit, [Cu-II{OCO-2,6-(CH3CONH)(2)C6H3}(2)(H2O)(2)], were synth esized; different hydrogen bond networks determined by X-ray analysis occur. While 2 has an infinite chain extended by intermolecular OH ... O hydrogen bonds, 1 has them between two molecules only. Their temper ature-dependent magnetic susceptibilities (-2J = 6.04(2) cm(-1) (1) an d 3.38(1) cm(-1) (2)) are related to the extent of the intermolecular hydrogen bond network. These results indicate that the formation of in termolecular hydrogen bonds changes the magnetic properties of materia ls. (C) 1998 Elsevier Science S.A. All rights reserved.
