The Mn(III) atom in the title complex, [Mn(C(18)H(18)N(2)O(4))(CHO(2))(H(2)O)]·2H(2)O, is O,N,N',O'-chelated by the deproton-ated Schiff base; the four chelating atoms form an approximate square, with the O atoms of the water mol-ecule and the formate ion in axial positions above and below the square plane. Two metal-bearing mol-ecules are linked by an O-H(water)⋯O hydrogen bond about a center of inversion, generating a hydrogen-bonded dinuclear species; adjacent dinuclear units are linked through the lattice water mol-ecules, forming a three-dimensional network.
标题配合物[Mn(C₁₈H₁₈N₂O₄)(CHO₂)(H₂O)]·2H₂O中的Mn(III)原子被去质子化的席夫碱O,N,N',O'-螯合；四个螯合原子形成一个近似正方形，水分子和甲酸根离子的O原子位于正方形平面上方和下方的轴向位置。两个含金属分子通过围绕一个反演中心的O-H(水)⋯O氢键相连，生成一个氢键连接的双核物种；相邻的双核单元通过晶格水分子相连，形成三维网络。
