title: Bis(4-amino-pyridine){2,2'-[1,2-phenyl-enebis(nitrilo-methanylyl-idene)]diphen-ol-ato}cobalt(III) nitrate.
abstract: In the title compound, [Co(C20H14N2O2)(C5H6N2)2]NO3, the Co(III) atom is coordinated in a slightly elongated octa-hedral geometry by the N2O2 donor set of the tetra-dentate Schiff base ligand and by the pyridine N atoms of two trans-arranged monodentate 4-amino-pyridine mol-ecules. The pyridine rings are aligned nearly perpendicularly to each other [dihedral angle = 82.28 (13)°]. The phen-oxy rings form dihedral angles of 12.37 (12) and 12.16 (14)° with the phenyl-ene ring. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the ions into a three-dimensional network.
