The crystals of bromhexine-HCl, $C_{14}$ H$_{21}$ N$_{2}$Br$_{2}$Cl, are orthohombic, space group Pca2 with a = 14.598(2)A, b=12.461(3)A, c =9 9.186(1) A and Z = 4. Intensity dat for 967 reflections (Fobs > 6.sigma.(F)) were collected on a Rigaku-Denki automatic four circle diffractometer. The structure was solved by the Patterson and Fourier methods. Refinements were carried out to the final R value of 0.082. The cyclohexane ring has a normal chair form and the benzene ring is planar. There are three independenet hydrogen bounds in the structure. One is an intermolecular hydrogen bond (N-H... Cl) and the others are intramolecular hydrogen bonds (N-H...Br, N$^{+}$-H...Cl$^{[-10]}$ ) Apart from the hydrogen bounding system the molecules are held together in the crystal by van der Waals force.e.
