The complex mol-ecule of the title compound, [Mn(C(13)H(10)N(4)O(8))(H(2)O)(2)] or [Mn(H(4)pbidc)(H(2)O)(2)] (H(6)pbidc = 2,2'-(propane-1,3-di-yl)bis-(1H-imidazole-4,5-dicarb-oxy-lic acid), has 2 symmetry with the twofold rotation axis running through the Mn(2+) cation and the central C atom of the propanediyl unit. The cation is six-coordinated by two N atoms and two O atoms from one H(4)pbidc(2-) anion and two water O atoms in a considerably distorted octa-hedral coordination. In the crystal, adjacent mol-ecules are linked through O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network.
标题化合物[Mn(C₁₃H₁₀N₄O₈)(H₂O)₂]或[Mn(H₄pbidc)(H₂O)₂]（H₆pbidc = 2,2'-（丙烷-1,3-二基）双-（1H-咪唑-4,5-二羧酸））的复杂分子具有二重对称性，二重旋转轴穿过Mn²⁺阳离子和丙二基单元的中心C原子。阳离子由来自一个H₄pbidc²⁻阴离子的两个N原子和两个O原子以及两个水分子的O原子以明显扭曲的八面体配位方式六配位。在晶体中，相邻分子通过O—H⋯O和N—H⋯O氢键连接成三维网络。
