{2,2′-[1,1′-(4-Aza-heptane-1,7-diyldinitrilo)diethyl-idyne] diphenolato}(pyridine)cobalt(III) hexa-fluoro-phosphate

The title complex, [Co(C22H27N3O2)(C5H5N)]PF6 or [Co{(Me-sal)2dpt}(py)]PF6, where (Me-sal)2dpt is 2,2′-[1,1′-(4-aza-heptane-1,7-diyldinitrilo) diethyl-idyne]diphenolate and py is pyridine, contains a penta-dentate (Me-sal)2dpt ligand which furnishes an N3O2 set, such that the N and O atoms of the salicyl-idene rings occupy trans positions in an equatorial plane, with the secondary amine N atom and the pyridine ligand in the axial positions. In the observed conformation of the penta-dentate ligand, the salycil-idene rings are bent away from the axial position occupied by the secondary amine N atom. The geometry of the resulting CoN4O2 coordination could be described as distorted octa-hedral.
