Abstract

Palladium-rhodium and platinum-rhodium heterobimetallic bridged dithiolate complexes of general formula [(P-P)M(mu-S-S)Rh(COD)]ClO4 (COD = 1,5-cyclooctadiene. For M = Pt: P-P = (PPh3)(2) and S-S = EDT2- (1,2-ethanedithiolate) (1), PDT2- (1,3-propanedithiolate) (2), and BDT2-(1,4-buthanedithiolate) (3); P-P = dppb (1,4-bis(diphenylphosphino)butane)and S-S = EDT2- (4), PDT2- (5), and BDT2- (6); P-P = dppp (1,3-bis(diphenylphosphino)propane) and S-S = EDT2-(7), PDT2- (8), and BDT2- (9),For M = Pd: P-P = dppb and S-S = EDT2- (10), PDT2- (11), and BDT2- (12); P-P = dppp and S-S = EDT2- (13), PDT2- (14), and BDT2- (15)) have been prepared. The crystal structures for complexes 1-3, 6, 9, and 12 ha iie been determined, and hinged structures were found with angles between local coordination planes MS2Rh ranging from 111.27 degrees forcomplex 1 to 151.34 degrees for complex 3.
