Bis{2-[(pyridin-2-yl)methyl-idene-amino]-benzoato-κ(3) N,N',O}chromium(III) nitrate monohydrate.

Abstract

The title complex salt hydrate, [Cr(C13H9N2O2)2]NO3·H2O, comprises discrete cations, nitrate anions and solvent water mol­ecules. The CrIII atom is octa­hedrally coordinated by two anionic Schiff base ligands with the O atoms being cis. The two ligands differ significantly with dihedral angles between the pyridine and benzene rings of 4.8 (2) and 24.9 (2)°. The nitrate anion and solvent water mol­ecule were modelled as being disordered, with the major components having site-occupancy values of 0.856 (14) and 0.727 (16), respectively. The crystal is built of alternating layers of cations and of anions plus water mol­ecules, stacked along the c axis.
