Designing ligands with the right bite
WebIt is defined as the solid angle formed with the metal at the vertex and the outermost edge of the van der Waals spheres of the ligand atoms at the perimeter of the cone (see figure). Tertiary phosphine ligands are commonly classified using this parameter, but the method can be applied to any ligand. WebCertain ligands may have natural bite angles that work better in some cases than in others. Propose the optimum bite angle in each of the following geometries. Problem CC4.5. Certain ligands tend to give a certain range of bite angles. Use the suggested criterion to predict which ligand in each pair would give the larger bite angle.
