Diaqua-bis-(pyridine-2-carboxyl-ato-κN,O)manganese(II) dimethyl-formamide hemisolvate.

ABSTRACT: There are two crystallographically independent complex mol-ecules with very similar geometries in the unit cell of the title compound, [Mn(C(6)H(4)NO(2))(2)(H(2)O)(2)]·0.5C(3)H(7)NO. The central ion is situated in a distorted octa-hedral environment of two N- and four O-donor atoms from two pyridine-2-carboxyl-ate ligands and two cis-disposed water mol-ecules. The carboxyl-ate ligands are coordinated in a chelate fashion with the formation of two five-membered rings. In the crystal, the complex mol-ecules are connected by O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the uncoordinated carboxyl-ate O atoms, thus forming hydrogen-bonded walls disposed perpendicularly to the bc plane.
