Abstract

The structure of p-bromophenylazo-bis-acetoxime (C12H17N4O2Br) has been solved by direct methods with X-ray diffraction data collected using CuKα radiation. The crystals are monoclinic, with a = 11.270(3), b=10.627(3), c = 12.631(1)Å, β = 97.50(2)° and space group P21/n. The structure was refined to an R value 0.046. The crystal structure analysis clearly indicated the presence of intra-molecular hydrogen bonding and the existence of an N–H bond, thus supporting tautomerism.
