    Kinetic studies of the chirality inversion of a series of mono- and bimetallic (p-cymene)(salicylaldiminato)RuII complexes with halo ligands (1and 2) in solution have been performed by means of the line-shape method, using 1H NMR spectroscopy to evaluate the signal exchange rates between diastereotopic protons in the p-cymene ligand. The activation parameters (DeltaHdouble dagger and DeltaSdouble dagger) associated with the flipping molecular mobility were determined from variable-temperature NMR analyses, and it was found that the neutral halo complexes 1 and 2 exhibit much lower enthalpies and entropies than the corresponding cationic pyridine analogues 3.
