The title complex, {Mn(C(10)H(8)N(2))(2)(H(2)O)(2)(2)}(n), contains an octa-hedrally coordinated Mn(II) cation and 2-(2-carboxy-phenyl-disulfan-yl)benzoate anions. The Mn(II) center is situated on a crystallographic center of inversion and is coordinated by four 4,4'-bipyridine (4,4'-bipy) ligands and two water mol-ecules. The 4,4'-bipy ligands act as bridging ligands, producing a fishing-net-like two-dimensional framework. In the crystal structure, this positively charged framework is charge balanced by 2-(2-carboxy-phenyl-disulfan-yl)benzoate anions that form a separate anionic two-dimensional framework via inter-molecular O-H⋯O hydrogen bonds and C-H⋯π stacking inter-actions. Additional inter-molecular O-H⋯O hydrogen bonds link the cationic and anionic frameworks to form the three-dimensional crystal structure.
标题配合物{Mn(C₁₀H₈N₂)₂(H₂O)₂₂}ₙ包含一个八面体配位的Mn(II)阳离子和2-(2-羧基苯基二硫烷基)苯甲酸根阴离子。Mn(II)中心位于一个晶体学反演中心上，由四个4,4'-联吡啶（4,4'-bipy）配体和两个水分子配位。4,4'-bipy配体作为桥连配体，形成一个类似渔网的二维框架。在晶体结构中，这个带正电荷的框架通过2-(2-羧基苯基二硫烷基)苯甲酸根阴离子实现电荷平衡，这些阴离子通过分子间O-H⋯O氢键和C-H⋯π堆积相互作用形成一个独立的阴离子二维框架。额外的分子间O-H⋯O氢键将阳离子和阴离子框架连接起来，形成三维晶体结构。
