Heterobimetallic Re=Pd complexes bridged by eta(1):eta(5)-Ph(2)PC(5)H(4) ligand. Synthesis, electronic and crystal structure of (CO)(2)(PR(3))(eta(5)-C(5)H(4)PPh(2))Re-PdCl(2), R = Me and OMe.
The new rhenium complexes (eta(5)-C(5)H(4)PPh(2))Re(CO)(2)(PR(3)) (R = Me (1) and OMe (2)) were prepared photochemically from (eta(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))(eta(5)-C(5)H(4)PPh(2))Re-PdCl(2) (3) and (CO)(2)(P(OMe)(3))(eta(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 A in and 2.774 A in ). Relativistic functional density theory calculations have also been carried out in order to probe the bonding in these compounds.
