Fig. 2

Pb-L3 EXAFS of the precursor film. The fourier transform of the k-space EXAFS is plotted, weighted by k2. Solid lines are magnitude of the measured EXAFS, dashed lines are the fit. R represents misfit; lower is better. a Fit to I in all sites (equitorial and axial) of the precursor structure. b I in equitorial and Cl in axial sites. c Best fit has I in equitorial sites and in 9% of axial sites (rest is Cl)
