3-amino-4'-methyl-5-ethylbiphenyl-2,4-dicarbonitrile and 3-amino-4'-(n,n-diethylamino)-5-ethylbiphenyl-2,4-dicarbonitrile.
In the title compounds, C17H15N3 and C20H22N4, the methyl derivative crystallizes with two molecules in the asymmetric unit, while the N,N-diethylamino derivative crystallizes with one molecule per asymmetric unit. The biphenyl twist angle for both molecular structures is approximately 45 degrees. The molecular packing is stabilized by N-H...N hydrogen bonds.
