Patent ID: 8338629

Claim:
An organometallic precursor represented by Formula 1 below: L n M m L′ p X q (1) wherein M is a transition metal; L′ is a neutral ligand; X is an anion coordinated or uncoordinated to M; m is an integer of 1 to about 10, with the proviso that when m is about 2 or higher, M may be identical to or different from each other; p is an integer of 0 to about 40, and q is an integer of 0 to about 10, with the proviso that when p or q is about 2 or higher, L′ or X may be each independently identical to or different from each other, and both p and q are not zero; L is a carboxyhydrazide compound coordinated to a metal, which is represented by Formula 2: wherein R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 are each independently hydrogen, a substituted or unsubstituted C 1 -C 30 alkyl group or a substituted or unsubstituted C 6 -C 30 aryl group; G is oxygen, sulfur or NR 7 , in which N is nitrogen and R 7 is hydrogen, a substituted or unsubstituted C 1 -C 30 alkyl group or a substituted or unsubstituted C 6 -C 30 aryl group; and n is an integer of 1 to about 40, with the proviso that when n is about 2 or higher, L may be identical to or different from each other, and wherein the metal, M is selected from the group consisting of silver, gold, copper, palladium, platinum, osmium, rhodium, cobalt, nickel, cadmium, iridium and iron; L′ is a neutral ligand coordinated to a metal, which is a C 1 -C 20 organic compound containing an electron- donating atom selected from the group consisting of nitrogen, phosphorus, arsenic, oxygen, sulfur, selenium and tellurium; and X may be coordinated or uncoordinated to a metal compound and is selected from the group consisting of OH − , CN − , NO 2 − , NO 3 − , trifluoroacetate, tetraalkylborate, tetrahaloborate, hexafluorophosphate, triflate, tosylate, sulfate, carbonate, nitroxyl, azide, acetylacetonate, hydrozino benzoic acid, trifluoroantimonate and combinations thereof.
