An object is to provide an organometallic complex whose phosphorescence characteristics can be adjusted by varying the structure of a ligand. Alternatively, an object is to provide an organometallic complex capable of emitting yellow phosphorescence with high luminance. Alternatively, an object is to provide a light-emitting device with high added value. An organometallic complex which has a structure represented by a general formula (G1) below and at least one substituent group represented by a general formula (G2) below as a phenyl group and is formed in such a way that a phenylpyrazine derivative represented by a general formula (G0) below is ortho-metalated by an ion of a Group 9 metal or of a Group 10 metal is provided. Alternatively, a light-emitting element and a light-emitting device formed including the organometallic complex are provided.
