Acetato(aqua){6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methanylyl-idene)]diphenolato}cobalt(III) methanol disolvate.

Abstract

In the title complex, [Co(C18H18N2O4)(C2H3O2)(H2O)]·2CH3OH, the CoIII atom is hexa­coordinated by water and acetate groups in the axial positions and by the tetra­dentate Schiff base occupying equatorial positions. These axial bonds are longer than the equatorial bonds to the tetra­dentate Schiff base. Two mol­ecules form a dimer through strong hydrogen bonds from the coordinated water of one mol­ecule to the meth­oxy O atoms of an adjoining mol­ecule. There is extensive intra- and inter­molecular O—H⋯O hydrogen bonding between the coordinated water and acetate ligands and the methanol solvent mol­ecules. In addition, there are weak inter­molecular C—H⋯O inter­actions, which link the mol­ecules into a three-dimensional array.
