Abstract

The title dinuclear compound, [Tb(2)(C(7)H(5)O(3))(6)(H(2)O)(6)]·10H(2)O, lies on a center of inversion and the two Tb(III) atoms are bridged by two 4-hydroxy-benzoate anions; each metal atom is further coordinated by one monodentate anion and chelated by the third anion. The eight-coordinate geometry approximates a square anti-prism. Hydrogen bonds of the O-H⋯O type connect the uncoordinated water mol-ecules to the dinuclear species, forming a three-dimensional network.

摘要

标题双核化合物[Tb₂(C₇H₅O₃)₆(H₂O)₆]·10H₂O位于一个对称中心上，两个Tb(III)原子由两个4-羟基苯甲酸根阴离子桥连；每个金属原子还与一个单齿阴离子配位，并被第三个阴离子螯合。八配位几何结构近似于一个反四方棱柱。O—H⋯O型氢键将未配位的水分子与双核物种相连，形成一个三维网络。
