MS-TOF study of the formation of thiolato bridged rhodium oligomers

The complex [Cp*Rh(μ‐SPh)3RhCp*]Cl was used as a starting material to synthesize various oligomeric materials of the general formula [Cp*Rh(μ‐SPh)x(μ‐Cl)3–x{Rh(μ‐SPh)3}nRhCp*] (x = 1 to 3; n = 1 to 4), which are formally formed by insertion of nRh(SPh)3 units into one μ‐Rh–SPh bond. The insertion of Ir(SPh)3 was also observed to generate theheterotrimetallic species. All complexes were observed by using HRMS‐TOF and [Cp*Rh(μ‐SPh)3Rh(μ‐SPh)3RhCp*]Cl, [3+]Cl, was characterized by using X‐ray crystallography
