✦ Synopsis
Synthesis and Structure of Sulfur‐, Sulfur Monoxide‐, and Sulfur Dioxide‐Bridged Dimetallic Complexes of the Type [M(CO)(dppm)]~2~(μ‐S)(μ‐L) and (CO)~3~M'(dppm)~2~MX (M = Rh, Ir; M' = Mo, W, Mn; L = SO, SO~2~; L' = S, SO~2~; X = Cl, CO)
The homo‐ and heterodimetallic complexes [M(CO)(dppm)]~2~‐(μ‐S)(μ‐SO~2~) (M = Rh, Ir) (2a, b), (CO)~3~M'(dppm)~2~MCl (M' = Mo, W; M = Rh, Ir) (4a – c), and [(CO)~3~Mn(dppm)~2~‐ Rh(CO)] (6) by passing sulfur dioxide through their solutions. The X‐ray structure analysis of 5a shows the SO~2~ 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 [(Ir(CO)(dppm)]~2~(μ‐S)(μ‐SO) (3b). Passing H~2~S through a solution of 6, the sulfur‐bridged complex (CO)~3~Mn(dppm)~2‐~ Rh(CO) (8) is formed, accompanied by H~2~ elimination.
