Abstract

The new rhenium complexes (η 5 -C 5 H 4 PPh 2 )Re(CO) 2 (PR 3 ) (R = Me (1) and OMe (2)) were prepared photochemically from (η 5 -C 5 H 4 PPh 2 )Re(CO) 3 in the presence of PMe 3 or P(OMe) 3 . Further reaction of these ligands with PdCl 2 (NCPh) 2 in chloroform, produces the heterobimetallic complexes (CO) 2 (PMe 3 )(η 5 -C 5 H 4 PPh 2 )Re-PdCl 2 (3) and (CO) 2 (P(OMe) 3 )(η 5 -C 5 H 4 PPh 2 )Re-PdCl 2 (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.
