There are independent cations and four chloride anions in the crystal structure of the title complex, [Co(C(6)H(6)N(4))(2)(H(2)O)(2)]Cl(2). In each cation, the Co(II) cation is coordinated by four N atoms from two biimidazole and two O atoms of two water mol-ecules; one Co atom is at a position of site symmetry m, the other at a position of site symmetry 2/m. All Cl(-) ions and water mol-ecules are also located on the mirror plane. Each structural unit is connected through O-H⋯Cl and N-H⋯Cl inter-molecular hydrogen bonds, forming a three-dimensional supramolecular structure.
在标题配合物[Co(C₆H₆N₄)₂(H₂O)₂]Cl₂的晶体结构中，存在独立的阳离子和四个氯离子阴离子。在每个阳离子中，Co(II)阳离子由来自两个联咪唑的四个N原子和两个水分子的两个O原子配位；一个Co原子位于位点对称m的位置，另一个位于位点对称2/m的位置。所有的Cl⁻离子和水分子也位于镜面上。每个结构单元通过O—H⋯Cl和N—H⋯Cl分子间氢键相连，形成三维超分子结构。
