{sup 11}B NMR: A new tool for the determination of hapticity of tris(pyrazolyl)borate ligands
- Univ. of Rochester, NY (United States). Dept. of Chemistry
While X-ray crystallography provides reliable solid-state information, the assignment of hapticity in [HB(3,5-dimethylpyrazolyl){sub 3}]ML{sub n} (M = Rh, Ir, Pt) complexes in solution is complicated by the dynamic nature of the tris(pyrazolyl)borate ligand. {sup 1}H and {sup 13}C NMR spectroscopy is ambiguous as to the nature of the coordination environment around the metal center. {sup 11}B NMR data are shown to correlate with the hapticity of the tris(pyrazolyl)borate ligand, making it a useful tool for the rapid determination of solution-state structure of tris(pyrazolyl)borate metal complexes.
