In the title compound, {Co(C(10)H(8)N(2))(H(2)O)(4)(2)·2C(10)H(8)N(2)·2H(2)O}(n), slightly distorted octa-hedrally coordinated Co(II) ions situated on inversion centers are linked into polycationic chains through 4,4'-bipyridine tethering ligands. These are connected into supra-molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol-ecules. A twofold inter-penetrated primitive cubic supra-molecular network is formed by the inter-action of pseudo-layers by hydrogen bonding between aqua ligands and unligated 4,4'-bipyridine mol-ecules.
在标题化合物{Co(C₁₀H₈N₂)(H₂O)₄₂·2C₁₀H₈N₂·2H₂O}ₙ中,位于对称中心的Co(II)离子呈略微扭曲的八面体配位,通过4,4'-联吡啶连接配体连接成聚阳离子链。这些通过涉及水合配体、高氯酸根阴离子和未配位水分子的氢键连接成超分子层。通过水合配体与未配位的4,4'-联吡啶分子之间的氢键作用,伪层相互作用形成了一个具有双重互穿的原始立方超分子网络。
