LIGAND DETERMINATION OF A COPPER COMPLEX BY CU 2P X-RAY PHOTOELECTRON-SPECTROSCOPY

The copper 2p X-ray photoelectron spectra (XPS) of cupric complexes, t he structures of which have been well characterized, were measured. Th e intensity of the so-called ''shake-up'' satellite relative to the ma in line was also measured. It was found that the satellite intensity d ecreased as the cupric complex became covalent. It was also found usin g this satellite intensity that a cupric complex of (S)-3-aminohexahpd roazepine (abbreviated as S-ahaz), [Cu(S-ahaz)(2)](BF4)(2), is directl y coordinated by an F atom.
