Abstract

The title compound, [Co(C22H18N2O4)]·2CH2Cl2, was isolated from the reaction of N,N′(o-phenylene)bis(vanillalimine) (H2 L) with Co(SCN)2. The crystal structure contains a CoII ion surrounded by the L 2− ligand in a slightly distorted square-planar fashion. Intermolecular C—H⋯O hydrogen-bonding contacts between the dichloromethane solvent molecules and the methoxy or carboxylate O atoms are observed in the crystal structure. The planar complex molecules stack through inversion related π–π interactions between the six-membered rings of the vanillalimine half ligands. The distance between centroids is 3.498 (2) Å and the perpendicular distance is 3.345 Å. A partial stacking is observed with a centroid–centroid distance of 3.830 (2) Å, a perpendicular distance of 3.350 Å and a slippage of 1.856 Å.
