Abstract
The self-aggregation tendency of RAPTA complexes [Ru(η6-p- cymene)PTA(-R)Cl2]X, R = H (1BPh4 and IPF6) and Me (2BPh4 and 20Tf), and [Ru(η6-p-cymene)(PTA) 2Cl]X (3BPh4 and 3BF4)] in acetone-de was investigated by means of diffusion NMR spectroscopy. On increasing the concentration, the protonated species (1X) undergoes intercationic self-aggregation driven by hydrogen bonding that leads to the formation of 122+ dications and a small amount of 12X + ion triples. © 2008 American Chemical Society.File in questo prodotto:
