Abstract: In the title compound, [Co(C₂₈H₂₂N₂O₂)(C₅H₅N)₂]ClO₄·0.5CH₄O·0.5H₂O, each Co^III ion is coordinated by the tetradentate N,N'-bis(2-oxidobenzylidene)-1,2-diphenylethane-1,2-diamine ligand [Co-N = 1.900 (3) and 1.903 (3) Å; Co-O = 1.885 (3) and 1.891 (3) Å] and two pyridine ligands [Co-N = 1.967 (4) and 1.977 (3) Å] in a distorted octahedral geometry. The packing of the cations and anions forms voids of 258 Å³, which are filled by methanol and solvent water molecules with half occupancies. O-HO hydrogen bonds between solvent molecules, perchlorate anions and water molecules, and between water molecules and O atoms of the ligand, help to consolidate the crystal packing.
