Abstract
The new rhenium complexes (? 5-C 5H 4PPh 2)Re(CO) 2(PR 3) (R = Me (1) and OMe (2)) were prepared photochemically from (? 5-C 5H 4PPh 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)(? 5-C 5H 4PPh 2)Re-PdCl 2 (3) and (CO) 2(P(OMe) 3)(? 5-C 5H 4PPh 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. © 2010 The Royal Society of Chemistry.
