The cation in the title salt, C33H28FN3OPS+·Cl−, is highly twisted with the phosphonium group occupying a position almost normal to the central hydroxylbenzene ring [P—C—C—C tosrsion angle = −100.9 (3)°], and with the hydrazone substituent twisted out of the plane [C—C—C—N torsion angle = 13.1 (4)°]. The fluorobenzene ring is twisted out of the plane of the adjacent thiourea residue, forming a dihedral angle of 51.69 (10)°. The configuration about the C=N bond [1.281 (4) Å] is E, the O—H and N—H hydrogen atoms are syn, and in the thiourea residue, the N—H hydrogen atoms are anti, allowing for the formation of an intramolecular N—H...N hydrogen bond. In the crystal, dimeric aggregates mediated by N—H...S bonds are formed, which are linked to the Cl− anions by O—H...Cl hydrogen bonds. The four-component aggregates are linked into a three-dimensional structure by C—H...Cl interactions.
