Bis[(2-pyridyl)(2-pyridylamino)-methanolato]manganese(III) nitrate

The Mn-III atom in the title complex, [Mn(C11H10N3O)(2)]NO3, is coordinated by the two tridentate (2-pyridyl)(2-pyridylamino)methanolate 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 angstrom. The methanolate O atoms occupy the axial positions. The coordination geometry is thus octahedral. In the title compound, the cations are linked by nitrate anions via N-H center dot center dot center dot O hydrogen bonds to form one-dimensional chains. Moreover, the one-dimensional structure is stabilized by intermolecular edge-to-face aromatic pi-pi interactions with a center-of-inversion at a distance of ca 4.634 angstrom.
