Abstract: In the title compound, (C₇H₉N₄S)[In(C₇H₇N₄S)Cl₃]·C₂H₆O, the two (E)-1-(2-pyridylmethylene)thiosemicarbazone (pmtcH) units show different structures; the coordinated pmtc^- ligand is in the enol form but the free pmtcH₂⁺ cation is in the keto form. The In^III complex assumes a distorted octahedral coordination geometry. N-HN and N-HCl hydrogen bonding helps to stabilize the crystal structure.
