Synthesis and Structure of Sulfur-, Sulfur Monoxide-, and Sulfur Dioxide-Bridged Dimetallic Complexes of the Type 2(μ-S)(μ-L) and (μ-L') (M = Rh, Ir; M' = Mo, W, Mn; L = S, SO2; X = Cl, CO)

The homo- and heterodimetallic complexes 2-(μ-S)(μ-SO2) (M = Rh, Ir) (2a, b), (μ-SO2) (M' = Mo, W; M = Rh, Ir) (5a-c), and (μ-SO2) (7) with SO2 in a bridging position are easily prepared from the corresponding complexes 2(μ-S) (M =Rh, Ir) (1a, b) (M' = Mo, W; M = Rh, Ir) (4a-c), and (6) by passing sulfur dioxide through their solutions.The X-ray structure analysis of 5a shows the SO2 ligand in a bridging position, whereas one CO ligand is semibridging.Treatment of the same starting materials with thiirane S-oxide does not lead to the corresponding SO-bridged dimers, with the only exception of 1b, which yields the new SO complex (μ-S) (8) is formed, accompanied by H2 elimination.Key Words: A-Frame complexes / SO2-bridged complexes / S, SO, SO2 ligands / Insertion reactions
