Abstract
Crystals of the title compound are monoclinic (C20H22N2O2): space groupP21/n,a=11.800(3),b=13.820(2),c=11.004(3) Å,β=92.74(3)°. The structure was solved by direct methods and refined by block-matrix least-squares procedure to giveR=0.078 andRw=0.076 for 1960 reflections above 3σ(I). The two amide groups are not coplanar with respect to their benzene rings. An intramolecular N-H⋯O hydrogen bond was found in the molecules which are joined in chains by other strong N-H⋯O hydrogen bonds.
