Disclosed is an organometallic complex capable of variable phosphorescence characteristics and yellow emission at high luminance. The organometallic complex has a structure represented by a formula (G10), where at least one of R4, R5, R6, and R7 is a phenoxy group, M is a Group 9 metal or a Group 10 metal, and n is 2 when the central metal M is a Group 9 element, or n is 1 when the central metal M is a Group 10 element.; |

1. An organometallic complex represented by a formula (G10), wherein: R1 represents an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, an alkoxycarbonyl group having 1 to 5 carbon atoms, or a phenyl group; R2 and R3 separately represent hydrogen, an alkyl group having 1 to 4 carbon atoms, or a phenyl group; R4, R5, R6, and R7 separately represent hydrogen, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, halogen, a trifluoromethyl group, and a phenyl group; at least one of substituent groups R4, R5, R6, and R7 has a structure represented by a formula (G2): M represents a Group 9 element or a Group 10 element; n is 2 when M is a Group 9 element or 1 when M is a Group 10 element; and R8, R9, R10, R11, and R12 separately represent hydrogen, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, halogen, a trifluoromethyl group, or a phenyl group. |
