The title compound, [Co(C(10)H(8)N(2))(3)]Cl(3)·4H(2)O, contains discrete Co(bpy)(3) cations (bpy is 2,2'-bipyridine), Cl(-) anions and water mol-ecules. The Co(bpy)(3) complex cation exhibits C(2) symmetry with the twofold axis through the central Co atom and bis-ecting one bpy ligand and one of the Cl(-) anions. The four solvent water mol-ecules and the remaining two Cl(-) anions lie on a mirror plane. Hydrogen-bond inter-actions define a two-dimensional layer structure parallel to (100), which consists of seven-membered [Cl(2)(H(2)O)(5)], eight-membered [Cl(4)(H(2)O)(4)] and ten-membered [Cl(2)(H(2)O)(8)] rings.
标题化合物[Co(C₁₀H₈N₂)₃]Cl₃·4H₂O包含离散的[Co(bpy)₃]³⁺阳离子(bpy为2,2'-联吡啶)、Cl⁻阴离子和水分子。[Co(bpy)₃]³⁺络合阳离子具有C₂对称性,二重轴穿过中心Co原子并平分一个bpy配体和一个Cl⁻阴离子。四个溶剂水分子和其余两个Cl⁻阴离子位于一个镜面上。氢键相互作用定义了一个平行于(100)的二维层状结构,该结构由七元环[Cl₂(H₂O)₅]、八元环[Cl₄(H₂O)₄]和十元环[Cl₂(H₂O)₈]组成。
