I'm having difficult interpreting the following H1 NMR I have been given for Cu4OCl6(2-mepy)4.
The NMR spectra obtained with integration trace beneath. I'm not too sure how to rationalise the 4.5:1 ratio between the peaks nor the cause of the small broad peak at 115ppm (well to the left of the spectra).
I'm also not too sure why the H1 NMR range is so vast. I appreciate being bonded to metals the electron density is changed across the relevant proton environments but by that much?
Thanks a lot
