The temperature‐ and pressure‐dependent equilibria for the addition of an extra N , N ‐dimethylforrnamide (DMF) or trimethylphosphate (TMP) ligand onto [Nd (DMF) 8 ] 3+ ‐ and [Nd(TMP) 6 ] 3+ ‐species respectively have been measured by visible spectrophotometry. Complementary NMR. studies on other lanthanide ions show a gradual shift in preference for the lower coordination number across the lanthanide series.
