Patent ID: 7002033

Claim:
A chemical vapor deposition material represented by the following formula (1): Ru 3+ +L n X m Y l (1) wherein L is a ligand represented by the following formula (2): wherein R 1 , R 2 and R 3 are each independently a hydrogen atom, fluorine atom, trifluoromethyl group or hydrocarbon group having 1 to 10 carbon atoms, X is a hydrogen anion, halogen anion, monovalent hydrocarbon anion having 1 to 10 carbon atoms or ligand represented by the following formula (3): wherein R 4 , R 5 , R 6 , R 7 and R 8 are each independently a hydrogen atom, hydrocarbon group having 1 to 10 carbon atoms or trimethylsilyl group, with the proviso that when at least two out of R 4 , R 5 , R 6 , R 7 and R 8 are hydrocarbon groups having 1 to 10 carbon atoms, they may be bonded together to form a 4- to 8-membered ring, Y is a ligand represented by the following formula (4): where in R 9 , R 10 , R 11 , R 12 , R 13 and R 14 are each independently a hydrogen atom or hydrocarbon group having 1 to 10 carbon atoms, n is an integer of 1 to 3, m is an integer of 0 to 2, l is 0 or 1, and (n+m) is 3.
