Abstract

In the title compound, [Cd(2)Cr(2)O(8)(C(12)H(8)N(2))(4)]·2H(2)O, which was obtained by hydro-thermal reaction of CdCO(3) and phenanthroline with K(2)CrO(4) at 393 K, two distorted Cd(N(4)O(2)) octa-hedra are linked through μ(2)-bridging chromate anions, forming a centrosymmetric tetra-nuclear eight-membered ring complex. The water mol-ecules link the chromate O atoms via inter-molecular O-H⋯O hydrogen bonds. These aggregates pack to a three-dimensional network through weak inter-molecular C-H⋯O and C-H⋯π hydrogen-bonding contacts.

摘要

在标题化合物[Cd₂Cr₂O₈(C₁₂H₈N₂)₄]·2H₂O中，它是通过碳酸镉、邻菲罗啉与铬酸钾在393 K下进行水热反应得到的，两个畸变的Cd(N₄O₂)八面体通过μ₂-桥连铬酸根阴离子相连，形成一个中心对称的四核八元环配合物。水分子通过分子间O—H⋯O氢键连接铬酸根O原子。这些聚集体通过弱的分子间C—H⋯O和C—H⋯π氢键接触堆积成三维网络。
