The title compound, {(C(10)H(10)N(2))[Cd(SO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)]·2H(2)O}(n), consists of anionic chains of the Cd complex, diprotonated 4,4'-bipyridinium cations and uncoordinated water mol-ecules. In the anionic chain, the Cd atom lies on a center of inversion in an octa-hedral geometry. The midpoint of the coordinated bipyridine also resides on a center of inversion, as does the non-coordinated bipyridinium counterion. O-H⋯O and N-H⋯O hydrogen bonding inter-actions and π-π stacking inter-actions in the structure are responsible for the supra-molecular assembly.
标题化合物{(C₁₀H₁₀N₂)[Cd(SO₄)₂(C₁₀H₈N₂)(H₂O)₂]·2H₂O}ₙ由镉配合物的阴离子链、双质子化的4,4'-联吡啶阳离子和未配位的水分子组成。在阴离子链中，镉原子处于八面体几何构型的对称中心。配位联吡啶的中点以及未配位的联吡啶鎓抗衡离子也位于对称中心上。结构中的O-H⋯O和N-H⋯O氢键相互作用以及π-π堆积相互作用负责超分子组装。
