The stereochemistry in solution of the diastereoisomeric complexes cis-dichloro[(S)-a-methylbenzylamine][(S)- and (R)-3- phenyl-3-methoxybut-1-ene]platinum(II) has been determined by 1H-NMR spectroscopy: in the two species the ethereal ligand is involved by its oxygen atom in the formation of an interligand O···H–N hydrogen bond with the amine. The remarkable differentiation of the 195Pt resonances is due to the different positions of amine substituents with respect to the metal.
