Abstract
The dynamic behavior of three bisbipyridylruthenium(II)-nicotinamide complexes was demonstrated by temperature-dependent 1H NMR spectroscopy which revealed hindered rotation of nicotinamide in the XÂ =Â chlorido and XÂ =Â iodido complexes at ambient temperature. In contrast free rotation of nicotinamide on the NMR timescale was observed for the bisnicotinamide (XÂ =Â nicotamide) complex at 298Â K. DFT calculations suggested that hindered rotation is associated with intramolecular H-bonding which is strongest for the chlorido complex.147
