- Abstract
The monothiolato complexes [(η6- p-MeC6H4 iPr)2Ru2Cl2(μ-Cl)(μ-SR)] with R = CH2C6H5 ( 1), p-CH2C6H4NO2 ( 2), C10H15 ( 3), m-9-B10C2H11 ( 4) were synthesized by treating [(η6- p-MeC6H4 iPr)2Ru2Cl2(μ-Cl)2] with the corresponding thiols RSH. The reaction of p-cymene ruthenium dichloride dimer with thiols is well known to give the cationic trithiolato complexes [(η6- p-MeC6H4 iPr)2Ru2(μ-SR)3]+, but recently the intermediary dithiolato complexes [(η6- p-MeC6H4 iPr)2Ru2Cl2(μ-SR)2] could also be isolated and characterized in some cases. The monothiolato complexes 1- 4 now observed represent the missing link in the stepwise formation of the trithiolato complexes. The single-crystal X-ray structure analyses of complexes 1 and 2 show the two ruthenium atoms to be bridged by a chlorido ligand and by the thiolato ligand without a metal-metal bond, which is in accordance with the eighteen-electron rule.
