Abstract:

The intramolecular conformational exchange thermodynamics of cis-PtCl[1,1'bis(undecenylseleno)ferrocene](B11SeFcPt) in CDCl3 solution was studied by one dimensional proton NMR． The chemical equilibrium constants were obtained directly from the integration of the 1H NMR spectra and the enthalpy as a function of temperature for the conformational exchange of B11SeFcPt was calculated from the equilibrium constant.

Key words: Conformational exchange enthalpy, 1H NMR, Selenoferrocene complex of PtCl2
