Bis[4-chloro-2-(quinolin-8-yl­imino­meth­yl)phenolato-[kappa]3N,N',O]cobalt(III) trichlorido­methano­lcobaltate(II)

Abstract: The reaction of 4-chloro-2-(quinolin-8-yl­imino­meth­yl)phenol (HClQP) with cobalt(II) dichloride hexa­hydrate in methanol/chloro­form under solvothermal conditions yielded the title compound, [Co(C16H10ClN2O)2][CoCl3(CH3OH)]. The CoIII atom is six-coordinated in a slightly distorted octa­hedral geometry by four N atoms and two O atoms of two tridentate HClQP ligands, which are nearly perpendicular to each other, making a dihedral angle of 86.95°. The CoII atom is four-coordinated by three Cl atoms and one O atom from a methanol ligand in a distorted tetra­hedral geometry. The crystal packing is consolidated by inter­molecular O-H...Cl, C-H...Cl and C-H...O hydrogen bonds, forming a three-dimensional supra­molecular structure, in which [CoIICl3(CH3OH)] anions are connected via O-H...Cl and C-H...Cl hydrogen bonds into centrosymmetric dimers. Neighboring cobalt(III) complexes form dimers through C-H...O hydrogen bonds, as well as [pi]-[pi] stacking [centroid-centroid distances = 3.30 (2) Å] between the planar quinoline systems of one HClQP ligand and the phenolate ring of another.
