Crystal Structure of Guanabenz Acetate

Abstract

The crystal of the title antihypertension agent, C₈H₉Cl₂N₄·C₂H₃O₂, belongs to space group Pbca with the cell dimensions a = 13.389(5), b = 11.007(6), and c = 17.342(5)Å. The final R value is 0.060. The planar hydrazinecarboximidamide moiety is slightly inclined to the phenyl group. The acetate ion plays an important role to connect guanabenz molecules together by hydrogen bonds in the crystal.
