ABSTRACT:
The present invention provides a method of manufacturing a bis(cyclopentadienyl)ruthenium, comprising the step of synthesizing a bis(cyclopentadienyl)ruthenium by causing cyclopentadiene, ruthenium chloride and zinc powder to react in an alcohol solvent, wherein the synthesis of the bis(cyclopentadienyl)ruthenium comprises the step of mixing the cyclopentadiene and zinc powder in the alcohol solvent and thereafter adding ruthenium chloride portionwise while holding the temperature of the reaction system at from −70° C. to 20° C. A highly pure product can be obtained through purification of subliming bis(cyclopentadienyl)ruthenium having been synthesized in the synthesis step in an atmosphere under reduced pressure.
