Abstract
Provided is a novel organometallic complex which can be synthesized easily and emits phosphorescence, or a compound which emits red phosphorescence. The inventors focused on easy synthesis of an m-aminophenyl pyrazine derivative represented by the following general formula (G0), synthesized an organometallic complex having a structure in which the derivative is coordinated to a Group 9 or Group 10 metal ion, and further synthesized a useful substance which emits red phosphorescence.
