Salts (R4N)2[Pd2X4(CO)2] [R = Prn, Bun, or pentyl (Pnn); X = Cl or Br] have been prepared. From their i.r., and in some cases Raman, spectra it is concluded that they have carbonyl-bridged structures. The anions appear to be essentially planar in the solid Prn4N+ salts but in solution and as the salts of the larger cations they seem to be bent about the carbonyl bridge. I.r. spectra indicate that the polymeric complex (PdXCO)n (X = Cl or Br) has CO and X bridges alternately between palladium atoms. Phases of probable molecular forms (Prn4N)2[Pd4Cl6(CO) 4] and Pd6Cl6(CO)6(PhCN)2 have been obtained and their i.r. spectra studied. The work indicates that a previous report of [PdCl2(H)CO]- salts and a derived complex [PdCl2(CO)(AsPh3)] is in error.
