Bis(2-{[2-(2-hydroxybenzylamino)ethyl]aminomethyl}phenolato-κ3N,N′,O1)cobalt(III) nitrate monohydrate

Abstract

In the title compound, [Co(C16H19N2O2)2]NO3·H2O, the CoIII ion is located on an inversion center and is six-coordinated by two phenolate O atoms and four amino N atoms from two diamine ligands, forming an octahedral geometry. The water molecule and the nitrate anion are located close to an inversion center, and are thus equally disordered by symmetry. The crystal packing is stabilized by intermolecular O—H...O hydrogen bonds involving the uncoordinated water molecule and the free phenol hydroxyl group with the nitrate anion. N—H...O hydrogen bonds involving the amino groups and the nitrate anions connect the complex molecules along the c axis.
