AgNO3、Ln(NO3)3 (Ln = La、Eu 和 Tb)、d-青霉胺 (d-pen、H2L) 和 NiCl2 (或 CoCl2) 的自组装反应导致形成六种新化合物：(H3O)3[LnNi6Ag8L12Cl(Ac)(H2O)4](H2O)28 (Ln = La (1)；Eu (2)；和 Tb (3)) 和 (H3O)2[LnCo2Ag3L6](H2O)3 （Ln = La (4)；Eu (5)；和 Tb (6)）。单晶X射线分析表明，1、2和3是同晶的，并具有3D阴离子骨架，其中节点是八面体{Ni6Ag8S12Cl}簇，Ln3+离子和连接体是d-pen配体的CCHCOO链。此外，4、5和6也是同晶的，具有以三角双锥{Co2Ag3S6}簇、Ln3+为节点、以d-pen配体的CCHCOO链为连接体的3D阴离子框架。拓扑分析表明，两个系列的3d-4d-4f异质三金属骨架分别具有(3,3)连接的utg和(6,6)连接的pcu网络。框架坚固稳定。客体分子被去除后，孔隙率得以保留，可以带回客体...
The self-assembly reactions of AgNO3, Ln(NO3)3 (Ln = La, Eu, and Tb), d-penicillamine (d-pen, H2L), and NiCl2 (or CoCl2) lead to the formation of six new compounds: (H3O)3[LnNi6Ag8L12Cl(Ac)(H2O)4](H2O)28 (Ln = La (1); Eu (2); and Tb (3)) and (H3O)2[LnCo2Ag3L6](H2O)3 (Ln = La (4); Eu (5); and Tb (6)). Single crystal X-ray analyses show that 1, 2, and 3 are isomorphous and have a 3D anionic framework in which the nodes are octahedral {Ni6Ag8S12Cl} clusters, and Ln3+ ions and the connectors are the CCHCOO chains of the d-pen ligands. Moreover, 4, 5, and 6 are also isomorphous, possessing a 3D anionic framework with trigonal dipyramidal {Co2Ag3S6} clusters, Ln3+ as nodes, and the CCHCOO chains of the d-pen ligands as connectors. Topology analysis indicates that the two series of 3d–4d–4f heterotrimetallic frameworks have (3,3)-connected utg and (6,6)-connected pcu networks, respectively. The frameworks are rigid and stable. The porosity is retained after the guest molecules are removed and can take back guest...
