Abstract

X-ray powder diffraction data for the three title compounds are reported. The crystals of all three compounds are monoclinic and the space group is P21 (No. 4) in each case. (1R, 2R)-(−)- norpseudoephedrine hydrochloride has a = 5.4422(8) Å, b = 8.071(1) Å, c = 11.839(1) Å and P= 101.803(9)°. For (1S,2R)-(+)-nqrephedrine hydrochloride a = 8.457(1) Å, b = 10.337(2) Å, c = 12.575(3) Å, and β = 107.46(1)° and for(±)-norephedrine hydrochloride a = 7.4406(6) Å, b = 9.4557(6) Å, c = 14.5799(8) Å and β= 103.446(7)°.
