trans-Diaquabis(1H-imidazole-4,5-dicarboxylate-kappa2N3,O4)manganese(II).
In the title compound, [Mn(C(5)H(3)N(2)O(4))(2)(H(2)O)(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) A and Mn-N = 2.201 (4) A] and two water molecules [Mn-O = 2.197 (4) A], 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.
