Reaction of m-amino-benzoic acid (MABA), di-ethano-lamine (DEA) and MnCl2·4H2O led to the formation of the title salt, Mn(C4H11NO2)22. In the complex cation, the Mn(2+) ion is located on an inversion centre and is coordinated by two symmetry-related tridentate DEA mol-ecules, leading to the formation of a slightly distorted MnN2O4 octa-hedron. The MABA(-) counter-anions are connected to the complex ion by a pair of rather strong O-H⋯O hydrogen bonds, yielding a 1:2 supra-molecular aggregate. Much weaker N-H⋯O hydrogen bonds connect neighbouring aggregates into a three-dimensional network structure.
间氨基苯甲酸（MABA）、二乙醇胺（DEA）与四水合氯化锰（MnCl₂·4H₂O）反应生成了标题盐Mn(C₄H₁₁NO₂)₂₂。在络合阳离子中，Mn(2+)离子位于一个对称中心上，并由两个对称相关的三齿DEA分子配位，形成了一个稍有畸变的MnN₂O₄八面体。MABA(-)抗衡阴离子通过一对相当强的O-H⋯O氢键与络合离子相连，形成了1:2的超分子聚集体。弱得多的N-H⋯O氢键将相邻的聚集体连接成三维网络结构。
