In the title complex, [Mn(C(8)H(4)O(7)S)(C(12)H(8)N(2))(2)], the Mn(II) atom is chelated by one 4-carb-oxy-2-sulfonato-benzoate anion and two phenathroline (phen) ligands in a distorted octa-hedral MnN(4)O(2) geometry. The benzene ring of the 4-carb-oxy-2-sulfonato-benzoate anion is twisted with respect to the two phen ring systems at dihedral angles of 66.38 (9) and 53.56 (9)°. In the crystal, inter-molecular O-H⋯O and C-H⋯O hydrogen bonding links the mol-ecules into chains running parallel to [100]. Inter-molecular π-π stacking is also observed between parallel phen ring systems, the face-to-face distance being 3.432 (6) Å.
在标题配合物[Mn(C₈H₄O₇S)(C₁₂H₈N₂)₂]中，Mn(II)原子由一个4-羧基-2-磺酸基苯甲酸根阴离子和两个菲咯啉（phen）配体螯合，形成扭曲的八面体MnN₄O₂几何构型。4-羧基-2-磺酸基苯甲酸根阴离子的苯环相对于两个菲咯啉环系统扭转，二面角分别为66.38 (9)°和53.56 (9)°。在晶体中，分子间的O—H⋯O和C—H⋯O氢键将分子连接成平行于[100]的链。在平行的菲咯啉环系统之间也观察到分子间的π-π堆积，面对面距离为3.432 (6) Å。
