Tris(1H-imidazole-κN (3))(7-oxabicyclo­[2.2.1]heptane-2,3-dicarboxyl­ato-κ(3) O (2),O (3),O (7))cobalt(II) 3.35-hydrate

In the crystal structure of the title compound, [Co(C(8)H(8)O(5))(C(3)H(4)N(2))(3)]·3.35H(2)O, the central Co(II) ion is in a slightly distorted octa­hedral environment, coordinated by the bridg­ing O atom from the bicyclo­[2.2.1]heptane ligand, by two carboxyl­ate O atoms from two different carboxyl­ate groups and by three N atoms from imidazole ligands. Uncoordinated water mol­ecules, some of them disordered, are present in the crystal structure. In the crystal structure, mol­ecules are linked by O—H⋯O, N—H⋯O and O—H⋯N hydrogen-bonding inter­actions.
