    摘要: A facile synthesis of the precursor, Cp.sub.2 Mo.sub.2 (.mu.-S).sub.2 (.mu.-SH).sub.2, to novel heterobimetallic cluster compositions (e.g., Cp.sub.2 Mo.sub.2 Fe.sub.2 (.mu.-S).sub.2 (CO).sub.8 ; Cp.sub.2 Mo.sub.2 Ni.sub.2 (.mu..sub.3 -S).sub.4 (CO).sub.2 ; Cp.sub.2 Mo.sub.2 Co.sub.2 (.mu..sub.3 -S).sub.2 (.mu..sub.4 -S)(CO).sub.4 ; Cp.sub.2 Mo.sub.2 Fe.sub.2 (.mu..sub.3 -S).sub.4 (CO).sub.6 and Cp.sub.4 Mo.sub.2 Ni.sub.2 S.sub.4 and the subsequent synthesis and use of the heterobimetallic cluster compositions as highly active and selective catalysts for the hydrogenation of carbon monoxide. Such heterobimetallic cluster catalysts supported on alumina exhibit extraordinary activity and selectivity with respect to the formation of ethane without concommitant formation of C.sub.3, C.sub.4 and heavier hydrocarbons. The catalysts are contemplated as being useful for syngas conversion even in the presence of several ppm of H.sub.2 S or the like in the feedstream.
