H1 NMR Spectra of inorganic complex, Cu4OCl6(2-mepy)4
What you have there is a typical example of an H NMR spectrum of a paramagnetic compound. The formal oxidation state of the Cu here is Cu(II) resulting in d9 configuration. This means that there will be an unpaired d electron making the Cu atoms paramagnetic.

The lone electron in the Cu atoms disturbs the magnetic field the Hs' feel resulting in extreme chemical shifts and also provide a very efficient relaxation mechanism resulting in extreme peak broadening (in some cases you cant even see the resonances at all). The highest paramagnetic shift I have encountered so far was around 250 ppm for an Fe(II) complex I made. In another occasion we had resonances at 1200 ppm!

As for the peak broadening I had peaks of ν1/2 of a few thousands of Hz. The integration wont always make much sense with paramagnetic compounds either.
