Mono- and Bi-nuclear Complexes of Rhodium with Functionalised Diphosphine Ligands

Treatment of with R2PCH2CH2PR2 (R = C6H4SMe-2 or C6H4SPr-2) gives the ionic complexes Cl A.When R = C7H4NS (benzothiazolyl) or C8H7N2 (N-methylbenzimidazolyl), however, the partially substituted complexes B result.Treatment of B (R = C7H4NS) with CHCl3 results in oxidation and disproportionation to the salt 2 C .X-Ray diffraction analysis of C shows the cation to have a structure with P-P chelated dbtpe ligand on each RhCl unit spanning the two metals by P,N ligation.The anion has regular octahedral co-ordination.Reaction of dbtpe with two metals by P,N ligation.The anion has regular octahedral co-ordination.Reaction of dbtpe with (cod = cycloocta-1,5-diene) or gives D which also has two P-P chelated RhCl units linked by P,N ligation, as shown by an X-ray crystal structure analysis.Full spectroscopic details are given for these compounds and their possible inter-relationship is discussed.
