In the title compound, [Co(C(12)H(8)NO(2))(2)(H(2)O)(4)], the Co atom lies on a twofold rotation axis and has an N(2)O(4) octa-hedral coordination environment formed by four O atoms of water mol-ecules in the equatorial plane and two apical N atoms of pyridine groups. An intricate three-dimensional supra-molecular network is formed by multiple O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the uncoordinated carboxyl-ate groups.
在标题化合物[Co(C₁₂H₈NO₂)₂(H₂O)₄]中,Co原子位于一个二重旋转轴上,具有由赤道平面上四个水分子的O原子和两个吡啶基团的顶端N原子形成的N₂O₄八面体配位环境。配位水分子与未配位羧酸根基团之间通过多个O—H⋯O氢键形成了一个复杂的三维超分子网络。
