摘要 3d-4f配合物的分子结构和离子间磁性相互作用具有非常重要的意义,拟通过N,N′-二(邻-羟基-3-甲氧基苯甲基)草酰(H4L),[Cu2L]2.3H2O和Ln(acac)3.3H2O以摩尔比2∶1∶4的比例在N,N′-二甲亚砜中反应,合成含有3d-4f磁性离子相互作用的配合物CuLLn(acac)。同时,采用紫外-可见光谱法对该混合溶液的自组装反应过程进行跟踪监测,观察到了自组装反应过程。然而,从溶液中得到的蓝色晶体是Cu(acac)2,粉色粉末是LnHL。该反应过程为:2Ln(acac)3+Cu2L+H4L=2LnHL+2Cu(acac)2+2Hacac。 The aim complexes [ CuLLn (acac)], has been synthesized by the reaction of [ Cu2L] 2 ·3H2O, H4L with Ln(acac)3· 3H2O (1:2:4 mole ratio) in dimethyl sulphoxide (DMSO) solution. The self-assembly process of mixture solution was observed by Uv-Vis spectrum. And blue crystal Cu (acac) 2 and pink powder HLEr was separated from the mixture solution. From the experiment Phenomena, we deduced that the eaction may be as following: 2Er(acac)3 + Cu2L + H4L =2HLEr +2Cu(acac)2 + 2Hacac.
