The title compound, {[Mn(NH(2)C(6)H(4)SO(3))(2)(H(2)O)(2)]·2H(2)O}(n), was prepared under mild hydro-thermal conditions. The unique Mn(II) ion is located on a crystallographic inversion center and is coordinated by two -NH(2) and two -SO(3) groups from four 4-amino-benzene-sulfonate ligands and by two water mol-ecules in the axial positions, forming a slightly distorted octa-hedral coordination environment. The 4-amino-benzene-sulfonate anions behave as μ(2)-bridging ligands to produce a two-dimensional structure. In the crystal structure, inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds link the layers into a three-dimensional network.
标题化合物{[Mn(NH₂C₆H₄SO₃)₂(H₂O)₂]·2H₂O}ₙ是在温和水热条件下制备的。独特的Mn(II)离子位于晶体学反演中心，由来自四个4-氨基苯磺酸盐配体的两个-NH₂和两个-SO₃基团以及轴向位置的两个水分子配位，形成略微扭曲的八面体配位环境。4-氨基苯磺酸盐阴离子作为μ₂-桥连配体形成二维结构。在晶体结构中，分子间的N-H⋯O、O-H⋯O和C-H⋯O氢键将各层连接成三维网络。
