摘要：

In the title compound, [Mn(C5H3N2O4)(2)(H2O)(2)], the Mn-II atom lies on an inversion centre, is trans-coordinated by two N,O-bidentate 1H-imidazole-4,5-dicarboxylate monoanionic ligands [Mn-O=2.202 (3) Angstrom and Mn-N=2.201 (4) Angstrom] and two water molecules [Mn-O=2.197 (4) Angstrom], and exhibits a distorted octahedral geometry, with adjacent cis angles of 76.45 (13), 86.09 (13) and 89.20 (13)degrees. The complete solid-state structure can be described as a three-dimensional supramolecular framework, stabilized by extensive hydrogen-bonding interactions involving the coordinated water molecules, the carboxy O atoms and the protonated imidazole N atoms of the imidazole-4,5-dicarboxylate ligands.
