The title complex, {[Mn(C(14)H(6)O(8)S(2))(C(12)H(8)N(2))(2)]·4H(2)O}(n), exhibits a chain-like polymeric structure with 9,10-dioxo-anthracene-1,5-disulfonate anions bridging Mn(II) atoms in a bis-monodentate mode. The unique Mn(II) atom is located on a crystallographic centre of inversion. Four N atoms from two chelating 1,10-phenanthroline ligands and two sulfonate O atoms from two symmetry-related 9,10-dioxoanthracene-1,5-disulfonate anions give rise to a slightly distorted octa-hedral coordination environment around the Mn(II) centre. The centroid of the central ring of the anthraquinone ligand represents another crystallographic centre of inversion. In the crystal structure, inter-ligand π-π stacking [centroid-to-centroid distances 3.532 (1) and 3.497 (3) Å] and inter-molecular O-H⋯O hydrogen-bonding inter-actions assemble the chains into a three-dimensional supra-molecular network.
标题配合物{[Mn(C₁₄H₆O₈S₂)(C₁₂H₈N₂)₂]·4H₂O}ₙ呈现出链状聚合物结构，其中9,10 - 二氧代蒽 - 1,5 - 二磺酸根阴离子以双单齿模式桥连Mn(II)原子。独特的Mn(II)原子位于晶体学反演中心。来自两个螯合的1,10 - 菲咯啉配体的四个N原子以及来自两个对称相关的9,10 - 二氧代蒽 - 1,5 - 二磺酸根阴离子的两个磺酸根O原子在Mn(II)中心周围形成了略微扭曲的八面体配位环境。蒽醌配体中心环的质心代表另一个晶体学反演中心。在晶体结构中，配体间的π - π堆积[质心到质心距离为3.532(1)和3.497(3) Å]以及分子间的O - H⋯O氢键相互作用将链组装成三维超分子网络。
