Abstract: In the structure of the title monomeric phosphorosilicate, C₄₂H₃₅O₃PSi₂ or PhP(=O)(OSiPh₃)₂, there are notable differences in the chemically equivalent P^V-O-Si angles [141.59  (16) and 152.38  (18)°] and the two P-O(-Si) distances [1.546  (3) and 1.566  (3)  Å]. There is also a significant C-HO=P hydrogen bond which links molecules into extended chains along [100].
