通过顺式封端的钯（II）受体与三羧酸酯和联吡啶供体的无模板三组分自组装反应制备了Pd-6分子笼[{（tmen）Pd}（6）（bpy）（3）（tma）（2）]（NO3）（6）[1;其中tmen = N，N，N，N-四甲基乙二胺，bpy = 4，4 '-联吡啶，H（3）tma =均苯三甲酸].配合物1代表了结合阴离子和中性连接体的限定形状的3D钯（II）笼的第一个实例。还通过NMR研究监测了该笼的客人诱导的排他性形成。
A Pd-6 molecular cage [{(tmen)Pd}(6)(bpy)(3)(tma)(2)](NO3)(6) [1; where tmen = N,N,N,N-tetramethylethylene diamine, bpy = 4,4'-bipyridyl, and H(3)tma = trimesic acid] was prepared via the template-free three-component seff-assembly of a cis-blocked palladium(II) acceptor in combination with a tricarboxylate and a dipyridyl donor. Complex 1 represents the first example of a 3D palladium(II) cage of defined shape incorporating anionic and neutral linkers. Guest-induced exclusive formation of this cage was also monitored by an NMR study.
