Abstract
The crystal and molecular structures of three 4-methylmorpholimum chlorides have been determined. The corresponding bond lengths and angles are the same in all three molecules and the methyl and phenyl groups are equatorially linked to the morpholine ring. The chlorine atoms are strongly hydrogen bonded to the protonated nitrogen atoms. The distances of the N-atom from the centers of the equatorial phenyl groups have an average value of 4.727 Å, while in one compound, BENZYL, this distance from the axial phenyl group is 6.08 Å.
