Abstract: In the title compound, (C₁₅H₁₂N₃O)[Cr(C₁₅H₁₀N₃O)(NCS)₃]·CH₄O, the Cr^III atom is coordinated by two N atoms and one O atom from the tridentate 1-(2-pyridyldiazenyl)-2-naphtholate (PAN) ligand and three N atoms from thiocyanate ions in a distorted octahedral arrangement. Another uncoordinated and protonated PAN molecule and a methanol solvent molecule are present in the asymmetric unit. The crystal packing is stabilized by - interactions [centroid-centroid separation 3.594 (4) Å] and O-HN and O-HS hydrogen bonds.
