Figure 5
Model zirconium(IV) complexes used to evaluate the stability of the two coordination modes of the Tz ligand. The numbers are the G-parameters for the Tz ligands. The bottom figures illustrate how the bidentate ligands shield the metal – the colored portions of the sphere are ligands' `shadows' on a 12 Å sphere they would cast if the metal were replaced with a light source. The view is from the position of the Tz ligand down toward the metal. The shadow is blue for the Tz ligand, and red, fuchsia, and turquoise for the Cl atoms. |
