Abstract
The crystal structure of 6-bromo-2-cyano-4'-diethylamino-4-nitro6'-propionamidoazobenzene has been determined by single-crystal X-ray analysis. The crystals are monoclinic, a = 29.015(6), b = 10.867(2), c = 24.945(5) λ,β= 147.80(3)°, space group C2/c, Ζ = 8. The structure was refined to R = 0.091 and Ry, = 0.065 by block-diagonal least-squares methods, using 2364 independent reflections measured with a single-crystal diffractometer. The conformation found has the propionamide group trans to the Br atom, and is apparently stabilized by intramolecular hydrogen bonding.
