Crystal Structure of 2-(2,2-Dibromovinyl)-1-methyl-1H-imidazole-4,5-dicarbonitrile

Abstract

The crystal structure of 2-(2,2-dibromovinyl)-1-methyl-1H-imidazole-4,5-dicarbonitrile (C8H4Br2N4, Mr = 315.92) has been determined by single crystal X-ray diffraction analysis. The compound crystallizes in the monoclinic crystal system with space group P21/c and unit cell parameters: a = 15.144(2), b = 16.382(3), c = 8.267(1) A, β = 95.76(2)o and Z = 8. The final reliability index is 0.0297 for 2505 observed reflections. The two molecules of 2-(2,2-dibromovinyl)-4,5-dicyano-1-methylimidazole are localized in independent part of unit cell. The crystal packing is stabilized by C–H···N hydrogen bonds and Br···N intermolecular interactions.
