Asymmetric, disubstituted metallocene compounds have the general formula CpMCp′ where M is a metal selected from the group consisting of Ru, Os and Fe; Cp is a first substituted cyclopentadienyl or indenyl moiety that includes at least one substituent group D1; Cp′ is a second substituted cyclopentadienyl or indenyl moiety that includes at least one substituent group D1′. D1 is different from D1′. D1 is X; Ca1Hb1Xc1; Ca2Hb2Xc2(C═O)Ca1Hb1Xc1; or Ca2Hb2Xc2OCa1Hb1Xc1, where X is a halogen atom or nitro group; a1 is an integer between 2 and 8; b1 is an integer between 0 and 2(a1)+1−c1; c1 is an integer between 0 and 2(a1)+1−b1; b1+c1 is at least 1; a2 is an integer between 0 and 8; b2 is an integer between 0 and 2(a2)+1−c2; and c2 is an integer between 0 and 2(a2)+1−b2; and D1′ is X; Ca1Hb1Xc1; Ca2Hb2Xc2(C═O)Ca1Hb1Xc1; or Ca2Hb2Xc2OCa1Hb1Xc1, where X is a halogen atom or nitro group; a1 is an integer between 1 and 8; b1 is an integer between 0 and 2(a2)+1−cl; c1 is an integer between 0 and 2(a1)+1−b1; b1+c1 is at least 1; a2 is an integer between 0 and 8; b2 is an integer between 0 and 2(a2)+1−c2; and c2 is an integer between 0 and 2(a2)+1−b2. The compounds can be employed as precursors in film deposition processes.
