摘要：

A heteronuclear (CuGdIII)-Gd-II complex [(CuLGdIII)-L-II(NO3)(3)] with the hexadentate Shiff-base compartmental ligand N,N-ethylene-bis(3-ethoxysalicylaldiimine) (H2L) has been synthesized and structurally characterized. The intermolecular semicoordination of nitrate oxygen to copper(II) results a one-dimensional zigzag chain, which are linked by H-bonding to form a two-dimensional sheet. Magnetic studies reveal ferromagnetic interaction within the dinuclear core and antiferromagnetic interaction propagated through the extended network (J = 4.04 cm(-1), zJ' = -0.027 cm(-1), g(Cu) = 2.109, g(Gd) = 2.001, where H = -2JS(Cu) (.) S-Gd + beta(g(Cu) (.) S-Cu + g(Gd) (.) S-Gd)H - zJ'<S-4Z>S-4Z). (C) 2002 Published by Elsevier Science B.V.
