“…103 The complexes [(PdXL) 2 CO] n , containing stabilising ligands of the type of arsine (L = AsPh 3 ) or stibine (L = SbPh 3 ) have been obtained on partial substitution of carbonyl and acido-ligands in palladium(+1) carbonyl halides and carbonyl acetate complexes by organoelement ligands. 104 The complexes have been characterised by elemental analysis, ESCA, and IR spectroscopy. Judging from the n = 1710 ± 1890 cm 71 region, the carbonyl group in these compounds is involved in bridging coordination.…”
