WebThe concept of cone angle is most easily visualized with symmetrical ligands, e.g. PR 3. But the approach has been refined to include less symmetrical ligands of the type PRR′R″ as well as diphosphines. In such asymmetric cases, the substituent angles' half angles, θ 2, are averaged and then doubled to find the total cone angle, θ. WebCone Angle.
