Popis:	The monothiolato complexes [(η6-p-MeC6H4iPr)2Ru2Cl2(μ-Cl)(μ-SR)] with R = CH2C6H5 (1), p-CH2C6H4NO2 (2), C10H15 (3), m-9-B10C2H11 (4) were synthesized by treating [(η6-p-MeC6H4iPr)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-MeC6H4iPr)2Ru2(μ-SR)3]+, but recently the intermediary dithiolato complexes [(η6-p-MeC6H4iPr)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.
