In the asymmetric unit of the title complex, [Mn(C(7)H(5)O(3))(2)(C(14)H(12)N(2))(H(2)O)]·0.5C(14)H(12)N(2), the Mn(II) ion is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) mol-ecule, one water mol-ecule and two monodentate 2-hydroxy-benzoate anions in a distorted trigonal-bipyramidal geometry. The OH group of the 2-hydroxy-benzoate anion is disordered over two positions with site-occupancy factors of 0.5. The asymmetric unit is completed with by an uncoordinated half-mol-ecule of dmphen, disordered about a crystallographic twofold axis. In the crystal structure, mol-ecules are linked into a two-dimensional framework by O-H⋯N, O-H⋯O and C-H⋯O hydrogen bonds. The packing of the structure is further stabilized by π-π stacking inter-actions involving dmphen mol-ecules, with centroid-centroid separations of 3.8027 (3) and 3.6319 (3) Å.
在标题配合物[Mn(C₇H₅O₃)₂(C₁₄H₁₂N₂)(H₂O)]·0.5C₁₄H₁₂N₂的不对称单元中，Mn(II)离子由一个双齿的2,9-二甲基-1,10-菲咯啉（dmphen）分子、一个水分子和两个单齿的2-羟基苯甲酸根阴离子以扭曲的三角双锥几何构型配位。2-羟基苯甲酸根阴离子的OH基团在两个位置上无序，占位因子为0.5。不对称单元由一个未配位的dmphen半分子完成，该半分子围绕一个晶体学二重轴无序。在晶体结构中，分子通过O-H⋯N、O-H⋯O和C-H⋯O氢键连接成二维框架。结构的堆积通过涉及dmphen分子的π-π堆积相互作用进一步稳定，质心间距为3.8027 (3) 和3.6319 (3) Å。
