Abstract: The structure of the title monomeric phosphosilicate, C₅₄H₄₅O₄PSi₃·0.263CH₂Cl₂ or (Ph₃SiO)₃PO·0.263CH₂Cl₂, is reported and is the first of a phosphosiloxane molecule with the general formula (R₃SiO)₃PO. Although the three P^V-O-Si angles are remarkably similar [143.57  (16), 144.47  (15) and 144.71  (15)°], the three P-O(Si) distances are remarkably different at 1.544  (2), 1.554  (2) and 1.561  (2)  Å.
