Abstract

The title compound, [Co(C13H9N2O2)2]·1.5C3H7NO, is formed as a neutral CoIIcomplex with dimethylformamide (DMF) solvent molecules. The CoIIatom has a distorted O2N4octahedral coordination sphere defined by two tridentate anionic Schiff base ligands with the O atoms beingcis. The coordination sphere around the CoIIatom is geometrically different from that reported for the co-crystal [Co(C13H9N2O2)2]·AA·H2O (AA is anthranilic acid). One of the DMF solvent molecules was modelled as being disordered about a crystallographic inversion centre with half-occupancy. The crystal structure is made up from alternating layers of complex molecules and DMF molecules parallel to (010). C—H...O hydrogen-bonding interactions between the complex molecules and the solvent molecules consolidate the crystal packing.
