The crystal structure of the title compound, [Mn(C7H5O2)(C10H6NO2)(C10H7NO2)], contains manganese(II) ions six-coordinated in a distorted octa­hedral environment. The equatorial plane is occupied by four O atoms, two from the carboxyl­ate group of the benzoate ion, the other two from carboxyl­ate/carboxyl groups of the quinaldate/quinaldic acid mol­ecules. 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 carboxyl­ate/carboxyl groups of adjacent quinaldate/quinaldic acid mol­ecules, forming zigzag chains that run along the c axis
