Summary The95Mo n.m.r. spectra for a series of molybdenum(0) complexes [Mo(CO)5L] (L=N,P,As, or Sb donor ligands) have been observed; resonances occur in the –1433 to –1864 ppm range for the twenty-six complexes with the95Mo shielding order being: N1J(95Mo–31P) coupling constants areca. 135 Hz and 220 Hz for phosphines and phosphites, respectively. Factors that influence the trends in coupling constants and chemical shifts are discussed. |
