The new rhenium complexes (η5-C5H 4PPh2)Re(CO)2(PR3) (R = Me (1) and OMe (2)) were prepared photochemically from (η5-C 5H4PPh2)Re(CO)3 in the presence of PMe3 or P(OMe)3. Further reaction of these ligands with PdCl2(NCPh)2 in chloroform, produces the heterobimetallic complexes (CO)2(PMe3)(η5-C 5H4PPh2)Re-PdCl2 (3) and (CO) 2(P(OMe)3)(η5-C5H 4PPh2)Re-PdCl2 (4). IR spectroscopy reveals that both complexes possess a Re-Pd interaction which was confirmed by X-ray crystallography (Re-Pd bond distance = 2.762 Å in 3 and 2.774 Å in 4). Relativistic functional density theory calculations have also been carried out in order to probe the bonding in these compounds.
