R. B. R. B. Gray 1 Introduction Transition metal ions in aqueous solutions typically are coordinated by multiple water molecules. Binding to a Lewis acidic metal center increases the Brønsted acidity of the water ligand such that, depending on the pH of the medium, one or two protons can be lost producing, respectively, hydroxo and oxo ligands. In some cases, the acidity of a coordinated water is so great that the oxo ligand cannot be protonated even in concentrated acid solutions.

With its axial lobes pointing directly at the imido s orbital, a pure dz2 orbital should lie above the Ni-NR p* orbitals. Electronic Structures of Oxo-Metal Ions 27 But, mixing with the 4s level produces a dz2 -s hybrid orbital with reduced density along the axis and increased density in the doughnut-shaped lobe in the equatorial plane that is devoid of ligands. The low coordination number in the molecule leads to z2-s hybridization, allowing strong NiNR p bonding. 5 Concluding Remarks Realistic targets that would constitute B&G approved oxo-wall violations include tetragonal trans-dioxo Ir(VII) complexes.
