Bis[(2-pyrid-yl)(2-pyridyl-amino)-methano-lato]manganese(III) nitrate

The Mn(III) atom in the title complex, [Mn(C(11)H(10)N(3)O)(2)]NO(3), is coordinated by the two tridentate (2-pyrid-yl)(2-pyridyl-amino)-methano-late ligands, forming a six-coordinate environment. The four pyridyl N atoms constitute the equatorial plane on which the manganese(III) ion lies; the coordination plane suffers a slight distortion as indicated by the average plane deviation of 0.058 Å. The methano-late O atoms occupy the axial positions. The coordination geometry is thus octa-hedral. In the title compound, the cations are linked by nitrate anions via N-H⋯O hydrogen bonds to form one-dimensional chains. Moreover, the one-dimensional structure is stabilized by inter-molecular edge-to-face aromatic π-π inter-actions with a center-of-inversion at a distance of ca 4.634 Å.
