Abstract
Crystals of the title compound are monoclinic (C26H25NO): space group P21/c, a=16.565(3), b=10.328(2), c=12.621(3) Å, β=104.02(3)°. The structure was solved by direct methods and refined by block-matrix least-squares to give R=0.056 and Rw=0.061 for 1613 reflections above 2 σ(I). The amide moiety is tilted by 19.3(2)° with respect to the mean aromatic ring plane. The two other gem phenyl rings subtend a dihedral angle of 112.2(4)° to each other. The molecules are joined in the solid by N-H⋯O hydrogen bonds.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
