Abstract

In the title compound, Sr(2)(C(8)H(6)O(8))(H(2)O)(4)), the Sr(II) ion is coordinated by six O atoms of four symmetry-related ligands and two water mol-ecules in a distorted bicapped trigonal-prismatic environment. The butane-1,2,3,4-tetra-carboxyl-ate ligands lie on inversion centers and bridge Sr(II) ions, forming a three-dimensional network. Within the three-dimensional structure, there are O-H⋯O hydrogen bonds involving the water mol-ecules and carboxyl-ate O atoms.

摘要

在标题化合物[Sr₂(C₈H₆O₈)(H₂O)₄]ₙ中，Sr(II)离子在扭曲的双帽三角棱柱环境中由四个对称相关配体的六个O原子和两个水分子配位。丁烷-1,2,3,4-四羧酸酯配体位于对称中心上并桥连Sr(II)离子，形成三维网络。在三维结构中，存在涉及水分子和羧酸酯O原子的O—H⋯O氢键。
