title: (Benzoato-κO,O')(quinoline-2-carboxyl-ato-κN,O)(quinoline-2-carboxylic acid-κN,O)manganese(II).
abstract: The crystal structure of the title compound, [Mn(C(7)H(5)O(2))(C(10)H(6)NO(2))(C(10)H(7)NO(2))], contains manganese(II) ions six-coordinated in a distorted octa-hedral environment. The equatorial plane is occupied by four O atoms, two from the carboxyl-ate group of the benzoate ion, the other two from carboxyl-ate/carboxyl groups of the quinaldate/quinaldic acid mol-ecules. The axial positions are occupied by the N atoms of the quinoline ring systems. The metal ion lies on a twofold rotation axis that bisects the benzoate ligand; the quinaldate and quinaldic acid ligands are therefore equivalent by symmetry, and the carboxylate/carboxyl groups are disordered. The complexes are joined together by hydrogen bonds between the carboxyl-ate/carboxyl groups of adjacent quinaldate/quinaldic acid mol-ecules, forming zigzag chains that run along the c axis.
