Abstract

Schiff bases have often been used as chelating ligands in the field of coordination chemistry, and their metal complexes have been extensively investigated due to their potential applications. It is known that reactions of N,N,O,O-donor Schiff bases ligands with transition metal ions have produced series of complexes with interesting structures and magnetic properties. A new complex prepared by the reaction of 2,2'-{propane-1,2-diyl-bis[nitrilo(E)methylidene]}bis(6-methoxyphenol) (H2L) with Co(III) ion is reported in this paper. The bicompartmental ligand acts in a tetradentate fashion. The H2L ligand is structurally characterized by elemental analysis, NMR and infrared spectroscopies, conductance and single X-ray diffraction.

The compound with Co(III) crystallizes in the monoclinic system in the space group P21/c with the unit cell parameters a = 13.168(2) Å, b = 15.795(2) Å, c = 15.882(2) Å, α = 90°, β = 110.703(16)°, γ = 90°. The cobalt (III) ion has slightly distorted octahedral coordination geometry.

In the structure of the mononuclear complex, the Co(III) cation is coordinated by two imine nitrogen atoms, two phenoxo oxygen atoms, from deprotonated Schiff base ligand and two oxygen atoms of water. There is also neighboring two molecule of DMF and one perchlorate anion non coordinating.
