For forming a thin ruthenium film of good quality by CVD method, it is necessary to form the thin film at low temperature. There hence is a desire for a ruthenium compound having a high reactivity to heat. This invention relates to a method of producing a ruthenium-containing film by CVD or the like using, as a raw material, a ruthenium complex mixture containing (2,4-dimethylpentadienyl)(ethyl-cyclopentadienyl)ruthenium and bis(2,4-dimethylpentadienyl)ruthenium, the amount of the latter compound being 0.1 to 100% by weight based on the weight of (2,4-dimethylpentadienyl)(ethylcyclopentadienyl)ruthenium, and the like.

This invention aims at providing (2,4-dimethylpentadienyl)-(ethylcyclopentadienyl)ruthenium which may contain its related structure compound, from which a ruthenium-containing thin film can be produced; a method of producing the same; a method of producing the ruthenium-containing thin film using the same; the ruthenium-containing thin film; and the like. The invention relates to producing the thin film using, as a precursor, (2,4-dimethylpentadienyl)(ethylcyclopentadienyl)ruthenium containing the related structure compound in an amount not more than 5% by weight, which can be obtained by separating the related structure compound from (2,4-dimethylpentadienyl)(ethylcyclopentadienyl)ruthenium containing the related structure compound.
