Abstract
Providing a novel organometallic complex represented by Structure Formula (G1). Ato Aindependently represent an alkyl group having 1 to 6 carbon atoms or a cycloalkyl group having 3 to 6 carbon atoms. Rto Rindependently represent any one of hydrogen, an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, and a cyano group, wherein at least one of Rto Rrepresents a cyano group. Rto Rindependently represent an alkyl group having 2 to 6 carbon atoms or a cycloalkyl group having 3 to 6 carbon atoms. Rand Rindependently represent any one of hydrogen, a methyl group, and an ethyl group. Note that Rand Rmay be bonded to each other to form a ring, and Rand Rmay be bonded to each other to form a ring.
