title: Diaqua-bis{5-carboxy-2-[(1H-1,2,4-triazol-1-yl)-meth-yl]-1H-imidazole-4-carboxyl-ato}-manganese(II).
abstract: In the title compound, [Mn(C(8)H(6)N(5)O(4))(2)(H(2)O)(2)], the Mn(II) ion is situated on an inversion center and is six-coordinated by two N and two O atoms from two L ligands (HL = 2-[(1H-1,2,4-triazol-1-yl)meth-yl]-1H-imidazole-4,5-dicarboxylic acid) and two water mol-ecules in a distorted octa-hedral geometry. In ligand L, the imidazole and triazole rings form a dihedral angle of 74.25 (8)°. Mol-ecules are assembled into a three-dimensional structure via inter-molecular O-H⋯O, O-H⋯N and N-H⋯N hydrogen-bonds, and π-π inter-actions with a short distance of 3.665 (2) Å between the centroids of the imidazole and triazole rings of neighbouring mol-ecules.
