Six mononuclear oxomolybdenum(V) and dioxomolybdenum(VI) complexes containing the hydrotris(3,5-dimethyl-1-pyrazolyl)borate ligand and a catechol- or phenol-based ligand with a pendant phosphate ester have been prepared and characterized by physical methods. Molecular modeling calculations show that the nonbonded Mo{hor ellipsis}P distances are restricted to 4-8 {angstrom}, depending upon the stereochemical constraints of the ligands. {sup 31}P NMR spectra of the Mo(V) complexes exhibit line broadening due to the d{sup 1} Mo(V) center. The observed relaxation times (T{sub 1} and T{sub 2}) are sensitive to the overall structure of the model compounds, and reasonable Mo{hor ellipsis}P distances can be calculated by using the Solomon equation. 32 refs., 1 fig., 1 tab.
