N-2-(2-BROMO-4,5-DIMETHOXYPHENYL)-1-(2,3,4-TRIMETHOXYPHENYL)ETHYLFORMAMIDE

C20H24BrNO6, M(r) = 454.3, monoclinic, Cc, a = 27.479 (4), b = 5.128 (1), c = 21.811 (3) angstrom, beta = 139.35 (1)-degrees, V = 2002 (1) angstrom 3, Z = 4, D(x) = 1.51 Mg m-3, Mo K-alpha radiation, lambda = 0.71069 angstrom, mu = 2.07 mm-1, F(000) = 936, T = 130 K, R = 0.030 for 4151 observed reflections. The X-ray study confirms that in the solid state the structure of the title compound is similar to that inferred from chemical and spectroscopic evidence. Steric hindrance from different chemical groups is minimized by the adoption of a staggered conformation at the central C(8)-C(9) bond, with aryl groups in an anti disposition. There is a delocalized orbital along the N-C-O fragment of the N-formylamino group.
