摘要：

In this paper we describe the synthesis and magnetic properties of a series of 3d-4f complexes of general formula [M(4)Ln(OH)(2)(chp)(4)(SALOH)(5)(H2O)(MeCN)(Solv)] (Solv = MeOH, MeCN, H2O; chp stands for deprotonated 6-chloro-2-hydroxypyridine (C5H3ClNO), SALOH stands for monodeprotonated 3,5-ditert-butylsalicylic acid (C15H21O3)) obtained by a solvent-free microwave assisted synthesis method. The Ni(ii) complexes (Ni4Gd, Solv = MeOH; Ni4Dy, Solv = MeCN) are not SMMs in the absence of an applied dc field. The replacement of Ni(ii) by Co(ii) (Co4La, Solv = MeOH; Co4Gd, Solv = H2O; Co4Gd-MeCN, Solv = MeCN; Co4Tb, Solv = MeOH; Co4Dy, Solv = H2O) results in improved SMM properties.
