Silver O and Cluster Compounds

[ (PhO)3P Fe(CO)2(NO)Ag]2, and [ HFe(C0) Ag]2],AgN03, has been described and the i.r. spectra of the complexes given.It was suggested that the neutral compounds are covalent oligomers with n = 3 or 4, which tend to ionize in donor solvents. 

Novel metal-metal bonded complexes [L2(CO)MAgox2] [L = PPha or P(p-tol)3 M = Rh or Ir ox = CF3CO2 or CIO4) have been obtained by refluxing Agox with the appropriate M carbonyl or phosphine in benzene.Analogous isobutyrato-complexes were also described, and structures (58) and (59) were indicated from n.m.r. and i.r. spectral measurements. 

paramagnetic [ Ag(CO)3] has been synthesized by co-condensing Ag vapour and CO at 6—15 The compound was characterized by mixed and isotopic substitution, frequency and intensity calculations and
