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)methyl]-1H-imidazole-4,5-dicarboxylic acid) and two water molecules in a distorted octahedral geometry. In ligand L, the imidazole and triazole rings form a dihedral angle of 74.25 (8)degrees. Molecules are assembled into a three-dimensional structure via intermolecular O-H center dot center dot center dot O, O-H center dot center dot center dot N and N-H center dot center dot center dot N hydrogen-bonds, and pi-pi interactions with a short distance of 3.665 (2) angstrom between the centroids of the imidazole and triazole rings of neighbouring molecules.
