Abstract:
A detailed analysis of the 35Cl/37Cl isotope shifts induced in the 128.8 MHz 195Pt NMR resonances of [PtCl n(H2O)6 - n]4 - n complexes (n = 6,5,4) in acidic solution at 293 K, shows that the unique isotopologue and isotopomer distribution displayed by the resolved 195Pt resonances, serve as a fingerprint for the unambiguous identification and assignment of the isotopic stereoisomers of [PtCl5(H2O)]- and cis/trans-[PtCl4(H2O)2]. © 2008 The Royal Society of Chemistry.
