and 2 can function as heterogeneous and reusable catalysts for the Strecker reaction of various imines. In addition, magnetic susceptibility measurements of complexes 1, 2 and 4 reveal antiferromagnetic coupling between the copper(II) ions. Complex 1 follows the Curie–Weiss law, while 2 and 4 obey the Bleaney–Bowers dinuclear model.
在水热条件下,包括调节反应比和反应温度,三维(3D)多孔[Cu 3(hbpdc)(OH)2(H 2 O)]·2H 2 O}(1),二维( 2D)薄片Cu 2(hbpdc)(H 2 O)2 } n(2),双核[Cu(hbpdc)0.5(H 2 O)2 ](3),二聚体[Cu 2(mbpdc)2(py)2 ]·9H 2 O(4)和单核[Cu(hbpdcH 2)(H 2O)2 ](5)是通过原位配体转化反应合成的,其中3,3'-二甲氧基-2,2-联吡啶-6,6'-二羧酸(mbpdcH 2)脱甲基为3,3'-二羟基-2,2'联吡啶-6,6'-二羧酸(hbpdcH 4)。hbpdcH 4配体的详细配位模式已通过单晶X射线衍射揭示。催化结果表明,聚合物1和2可用作各种亚胺的Strecker反应的多相且可重复使用的催化剂。另外,配合物的磁化率测量1,2和图4揭示了铜(II)离子之间的反铁磁耦合。复杂
