Abstract
The MnIII atom in the title complex, [Mn(C18H18N2O4)(CHO2)(H2O)]·2H2O, is O,N,N′,O′-chelated by the deprotonated Schiff base; the four chelating atoms form an approximate square, with the O atoms of the water molecule and the formate ion in axial positions above and below the square plane. Two metal-bearing molecules are linked by an O—Hwater⋯O hydrogen bond about a center of inversion, generating a hydrogen-bonded dinuclear species; adjacent dinuclear units are linked through the lattice water molecules, forming a three-dimensional network.
