In the structure of the title monomeric phosphorosilicate, C42H35O3PSi2 or PhP(=O)(OSiPh3)2, there are notable differences in the chemically equivalent PV—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—H...O=P hydrogen bond which links mol­ecules into extended chains along [100].

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
