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.
