The title compound, C21H15O4P·0.5C4H8O, contains an ordered phosphane oxide in a general position and a tetrahydrofuran solvent molecule disordered about a twofold axis. All three aldehyde substituents are nearly coplanar with their attached benzene rings, with C - C - C - O torsion angles in the range 1.64 (17)-4.24 (19)°. All three have different conformations with respect to the P=O group, one syn, one anti, and one gauche. Two of the aldehyde substituents form intermolecular C - H⋯O contacts.
