Mn(II)、Cu(II)、Co(II) 和 Ni(II) 盐与 2-(1-三唑)-1-羟基-1,1'-亚乙基二膦酸 (tahedpH4) 的水热反应生成四种新型金属膦酸盐，即 Mn2(tahedp)(H2O)2 (1)、 Cu2(tahedp)(H2O) (2)、Co(tahedpH2) (3) 和 Ni2(tahedpH2)2·(NH2CH2CH2NH2) (4)。在化合物 1 中，二聚体单元 {Mn12O2} 通过 O3-P1-O1 基团连接在一起，形成无机链。相邻的链进一步通过{Mn2O4N}五面体连接，形成起伏的无机层。无机层通过三唑基团桥联，形成三维框架结构。从拓扑结构来看，1的结构可以描述为前所未有的三节(4.66.83)2(42.62.82)(5.62)2拓扑网络。化合物2显示出柱状层状结构，其中{Cu12O2}二聚体通过O3-P1-O1基团连接在一起形成双链。双链和{−Cu2−O5−P2−O4−}2八元环通过O2和...的配位进一步连接。
Hydrothermal reactions of Mn(II), Cu(II), Co(II), and Ni(II) salts with 2-(1-triazole)-1-hydroxyl-1,1′-ethylidenediphosphonic acid (tahedpH4) lead to four novel metal phosphonates, namely, Mn2(tahedp)(H2O)2 (1), Cu2(tahedp)(H2O) (2), Co(tahedpH2) (3) and Ni2(tahedpH2)2·(NH2CH2CH2NH2) (4). In compound 1, dimeric units {Mn12O2} are linked together by the O3−P1−O1 groups forming an inorganic chain. The adjacent chains are further connected by {Mn2O4N} pentahedra to form an undulating inorganic layer. The inorganic layers are bridged by the triazole groups resulting in a three-dimensional framework structure. In the opinion of the topology, the structure of 1 can be described as an unprecedented trinodal (4.66.83)2(42.62.82)(5.62)2 topological network. Compound 2 shows a pillared layered structure in which the {Cu12O2} dimers are linked together by the O3−P1−O1 groups forming a double chain. The double chains and the {−Cu2−O5−P2−O4−}2 eight-membered rings are further linked through the coordination of O2 and ...
