Dichloro[(1E,1'E)-1,1'-(pyridine-2,6-diyl)diethanone bis(O-methyloxime)-kappa3N1,N2,N6]cobalt(II).
In the title compound, [CoCl2(C11H15N3O2)], the CoII ion is five-coordinated in a strongly distorted square-pyramidal arrangement, with one of the two Cl atoms located in the apical position, and the other Cl atom and the three N-donor atoms of the tridentate methyloxime ligand located in the basal plane. The non-H atoms, except for the Cl atoms, lie on a mirror plane. The two equatorial Co-Noxime distances are almost equal (mean 2.253 A) and are substantially longer than the equatorial Co-Npyridine bond [2.0390 (19) A]. The structure is stabilized by intra- and intermolecular C-H...Cl contacts, which involve one of the methyl C atoms belonging to the methyloxime groups.
