Phosphinoamino complexes of copper(I) and silver (I): A combined NMR and IR spectroscopy, and electrospray ionization and fast atom bombardment mass spectrometry analysis

Bidentate 'PN' and tetradentate 'P2N2' ligands form stable silver(I) complexes, which were characterized by NMR and IR spectroscopy. Conductivity measurements indicate an ionic nature of the compounds in solution. A thorough mass spectrometric study (electrospray ionization and fast atom bombardment) of these complexes and the corresponding Cu(I) analogues supports the NMR and IR structural information.
