Hydrogen bonding in C-substituted nitroanilines: sheets built from alternating R(2)(2)(12) and R(6)(6)(36) rings in 2-bromo-6-cyano-4-nitroaniline.
Molecules of the title compound (systematic name: 2-amino-3-bromo-5-nitrobenzonitrile), C(7)H(4)BrN(3)O(2), are linked by N-H...N and N-H...O hydrogen bonds [H...N 2.19A, N...N 3.019(4)A and N-H...N 157 degree, and H...O 2.17A, N...O 2.854(3)A and N-H...O 134 degree] to form (10-3) sheets built from alternating R(2)(2)(12) and R(6)(6)(36) rings, both of which are centrosymmetric.
