The reaction of [Mn(CO)5]- with SCCl2 in pentane at room temperature produces minor amounts of a mixture of Mn2(CO)9CS and Mn2(CO)10, isolated from the solution. The main reaction product, which is insoluble in pentane, consists of a CO- and Cl-containing ionic material. In the presence of 18-crown-6, [K(18-crown-6)][Mn(CO)4Cl2] is formed exclusively. The thiocarbonyl derivative, which could not be separated from Mn2(CO)10, was identified and characterized by mass, IR, and 55Mn NMR spectroscopic methods, which also showed that Mn2(CO)9CS exists as a mixture of the cis and trans isomers. Further, the formation of Mn2(CO)9CS was demonstrated by reactions with PPh3 and Br2.
