Abstract
In the title compounds,(C17)H15 N-3 and C-20 H-22 N-4, the methyl derivativ e crystallizes with two molecules in the asymmetric unit, while the N,N-die thylamino derivative crystallizes with one molecule per asymmetric unit. Th e biphenyl twist angle for both molecular structures is approximately 45 de grees. The molecular packing is stabilized by N-H . . . N hydrogen bonds.
