title: trans-Diaqua-bis[5-carb-oxy-2-(3-pyridyl)-1H-imidazole-4-carboxyl-ato-κN,O]manganese(II).
abstract: In the title compound, [Mn(C(10)H(6)N(3)O(4))(2)(H(2)O)(2)], synthesized by hydro-thermal reaction, the Mn(II) ion lies on an inversion centre and displays a distorted octa-hedral coordination geometry defined by the two imidazole N atoms and two carboxylate O atoms of the two trans-standing chelate ligands, and two O atoms of the water mol-ecules. A two-dimensional supra-molecular architecture is formed via N-H⋯O, O-H⋯N and O-H⋯O hydrogen-bonding inter-actions.
