Abstract: The title cocrystal, [Mn(C₁₉H₂₀N₂O₂)(C₅H₅N)(CH₃OH)]PF₆·[Mn(C₁₈H₁₈N₂O₂)(C₅H₅N)(CH₃OH)]PF₆, is a 1:1 co-crystal of two Mn^III complexes with Schiff base ligands. In each structure, the Mn^III centre is in a six-coordinate distorted octahedral N₃O₃ environment, with the N₂O₂ donor atoms of the tetradentate Schiff base ligand as the equatorial plane and the pyridine and methanol molecules in the two axial positions. The difference in the two components of the co-crystal, which are disordered over the same site, is the addition of a methyl group to one of the two methylene C atoms linking the imine N atoms of the Schiff base ligand in one component. In the crystal structure, intermolecular O-HO hydrogen bonds and weak intermolecular C-HO interactions link the molecules into a network. A weak C-HN intramolecular interaction is also observed in the structure of [Mn(C₁₉H₂₀N₂O₂)(C₅H₅N)(CH₃OH)]PF₆.
