A remarkable temperature-dependent, accidental degeneracy of 31P NMR chemical shifts in Ru(II) diphosphine/diimine complexes.
Several cis-RuX2((R)-BINAP)(diimine) complexes have been prepared, and many of these exhibit an unusual temperature-dependent, accidental degeneracy of the 31P shifts in their solution NMR spectra.
