title: Diaqua-[5,5'-dicarb-oxy-2,2'-(propane-1,3-di-yl)bis-(1H-imidazole-4-carboxyl-ato)]manganese(II).
abstract: 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.
