| Abstract: | Summary Silver(I) complexes with the P/O ambidentate phosphito- and phosphinito-ligands are shown to adopt P-bonded structures in solution by means of31P n.m.r. spectroscopy.1J(Ag, P) of AgP(O)(OEt)2 represents the largest one bond silverphosphorus coupling constant reported so far. AgP(O)(OEt)2 forms co-ordination complexes of the stoichiometry [Ag{P(O)(OEt)2}(PBu3n)n], n=1, 2 or 3 which were characterized by31P n.m.r. spectroscopy.The nomenclature accords with that used in the review of Roundhillet al.(1). |
