In the mononuclear complex molecule of the title compound, [Cr(C9H9O3)2Cl(H2O)]·0.5CH3CN, the CrIII atom displays an elongated octahedral coordination geometry. The dihedral angle between the benzene rings is 12.27 (11)°. Adjacent complex molecules are linked into dimers by O—H⋯O hydrogen bonds, generating rings of R12(6) and R12(5) graph-set motifs, and by aromatic π–π stacking interactions, with a centroid–centroid distance of 3.812 (2) Å. The crystal packing is further stabilized by intermolecular C—H⋯N hydrogen bonds. The C and N atoms of the acetonitrile solvent molecule are located on a crystallographic twofold axis.
