An object is to provide a novel organometallic complex capable of emitting phosphorescence, an organometallic complex which exhibits deep red emission, and a light-emitting element which provides deep red emission. Provided is an organometallic complex having a structure represented by the following General Formula (G1).
In the formula, R1, R2, R3, R4, R5, R6, R7, R8, and R9 represent substituents, and M is a central metal and represents either a Group 9 element or a Group 10 element.
