This angle indicates that the phosphorus atom is almost … WebOrganophosphines, like phosphine itself, are pyramidal molecules with approximate C 3v symmetry. The C–P–C bond angles are approximately 98.6°. The C–P–C bond angles are consistent with the notion that phosphorus predominantly uses the 3p orbitals for forming bonds and that there is little sp hybridization of the phosphorus atom.
