摘要：

A unique 3d-4f mixed metal trinuclear compound, [Cu2Gd(L)(2)(NO3)(2)]NO3 (1; H2L = 2,6-di(acetoacetyl)pyridine), is derived from a 'one-pot' reaction with H2L, Cu(NO3)(2).3H(2)O and Gd(NO3)(3).5H(2)O. Two L2- providing one central 2,6-diacylpyridine site and two terminal 1,3-diketonate sites hold two Cu-II ions and Gd-III ion and form a linear Cu-Gd-Cu trinuclear core. This compound shows ferromagnetic interaction between Cu-II and Gd-III. (C) 2002 Elsevier Science B.V. All rights reserved.
