What is claimed is: 1. An organic metal compound, having a structure of Formula (I): wherein, R 1 is C 5-10 cycloalkyl group, C 3-12 heteroaryl group, or C 6-12 aryl group; R 2 is independently hydrogen, halogen, C 1-12 alkyl group, C 5-10 cycloalkyl group, C 3-12 heteroaryl group, or C 6-12 aryl group. 2. The organic metal compound as claimed in claim 1 , wherein R 1 is cyclopentyl group, cyclohexyl group, phenyl group, biphenyl group, or naphthyl group. 3. The organic metal compound as claimed in claim 1 , wherein R 2 is independently hydrogen, fluorine, methyl group, ethyl group, propyl group, isopropyl group, n-butyl group, isobutyl group, sec-butyl group, tert-butyl group, pentyl group, hexyl group, cyclopentyl group, cyclohexyl group, octyl group, decyl group, dodecyl group, phenyl group, biphenyl group, or naphthyl group. 4. The organic metal compound as claimed in claim 1 , wherein the organic metal compound has a structure of Formula (II): wherein, R 2 is independently hydrogen, halogen, C 1-12 alkyl group, C 5-10 cycloalkyl group, C 3-12 heteroaryl group, or C 6-12 aryl group. 5. The organic metal compound as claimed in claim 4 , wherein R 2 is independently hydrogen, fluorine, methyl group, ethyl group, propyl group, isopropyl group, n-butyl group, isobutyl group, sec-butyl group, tert-butyl group, pentyl group, hexyl group, cyclopentyl group, cyclohexyl group, octyl group, decyl group, dodecyl group, phenyl group, biphenyl group, or naphthyl group. 6. The organic metal compound as claimed in claim 4 , wherein the organic metal compound is 7. The organic metal compound as claimed in claim 1 , wherein the organic metal compound has a structure of Formula (IV): wherein, R 1 is C 5-10 cycloalkyl group, C 3-12 heteroaryl group, or C 6-12 aryl group. 8. The organic metal compound as claimed in claim 7 , wherein R 1 is cyclopentyl group, cyclohexyl group, phenyl group, biphenyl group, or naphthyl group. 9. The organic metal compound as claimed in claim 1 , wherein the organic metal compound has a structure of Formula (VI): wherein, R 1 is C 5-10 cycloalkyl group, C 3-12 heteroaryl group, or C 6-12 aryl group. 10. The organic metal compound as claimed in claim 9 , wherein R 1 is cyclopentyl group, cyclohexyl group, phenyl group, biphenyl group, or naphthyl group. 11. An organic light-emitting device, comprising: a pair of electrodes; and an organic light-emitting element, disposed between the electrodes, wherein the organic light-emitting element comprises the organic metal compound as claimed in claim 1 . 12. The organic light-emitting device as claimed in claim 11 , wherein the organic light-emitting element comprises a light-emitting layer, wherein the light-emitting layer comprises a host material and the organic metal compound.
