title: Crystal structure of bis-(2-{[(pyridin-2-yl)methyl-idene]amino}-benzoato-κ(3) N,N',O)cobalt(II) N,N-di-methyl-formamide sesquisolvate.
abstract: The title compound, [Co(C13H9N2O2)2]·1.5C3H7NO, is formed as a neutral Co(II) complex with di-methyl-formamide (DMF) solvent mol-ecules. The Co(II) atom has a distorted O2N4 octa-hedral coordination sphere defined by two tridentate anionic Schiff base ligands with the O atoms being cis. The coordination sphere around the Co(II) atom is geometrically different from that reported for the co-crystal [Co(C13H9N2O2)2]·AA·H2O (AA is anthranilic acid). One of the DMF solvent mol-ecules was modelled as being disordered about a crystallographic inversion centre with half-occupancy. The crystal structure is made up from alternating layers of complex mol-ecules and DMF mol-ecules parallel to (010). C-H⋯O hydrogen-bonding inter-actions between the complex mol-ecules and the solvent mol-ecules consolidate the crystal packing.
