The crystal structure of the title compound, Mn(C(14)H(13)NO(2))(2)(H(2)O)(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.
标题化合物Mn(C₁₄H₁₃NO₂)₂(H₂O)₃₂的晶体结构由两个席夫碱2-甲氧基-6-(N-苯基甲亚胺基)苯酚(HL)配体和三个配位水分子组成。Mn(II)离子位于一个平分一个水分子O原子的二重轴上。五配位Mn原子的配位球由两个单齿HL配体和三个通过其O原子配位的水分子完成，形成扭曲的四方锥几何构型。在酚盐配体中，羟基H原子转移到亚胺N原子上。该H原子还参与分子内N-H⋯O氢键，使每个配体具有近乎平面的构象，每个配体的芳环之间的二面角为2.78(3)°和2.43(5)°。在晶体中，分子通过分子间O-H⋯O氢键相连。
