title: Triaqua-bis-{2-meth-oxy-6-[(phenyl-iminium-yl)meth-yl]phenolate-κO}manganese(II) dinitrate.
abstract: The crystal structure of the title compound, [Mn(C(14)H(13)NO(2))(2)(H(2)O)(3)](NO(3))(2), is comprised of two Schiff base 2-meth-oxy-6-(N-phenyl-carboximido-yl)phenol (HL) ligands and three coordinated water mol-ecules. The Mn(II) ion lies on a twofold axis that bis-ects one water O atom. The coordination sphere of the five-coordinate Mn atom is completed by the two monodentate HL ligands and three coordinated water mol-ecules binding through their O atoms, affording a distorted tetra-gonal-pyramidal geometry. In the phenolate ligands, the hy-droxy H atom transfers to the imine N atom. This H atom is also involved in an intra-molecular N-H⋯O hydrogen bond that imposes a nearly planar conformation on each ligand, with dihedral angles of 2.78 (3) and 2.43 (5)° between the aromatic rings of each ligand. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds.
