چکیده
The title compound, C7H13ClN2O2, synthesized by the reaction of 2-chloro-ethyl iso-cyanate and morpholine, crystallizes with four molecules in the asymmetric unit, which have similar conformations and comprise two pairs each related by approximate non-crystallographic inversion centres. Two of them have a modest orientational disorder of the 2-chloro-ethyl fragments [occupancy ratio of 0.778 (4):0.222 (4)]. In the crystal, mol-ecules are linked by N-H⋯O=C hydrogen bonds, forming three crystallographically different kinds of infinite hydrogen-bonded chains extending along [001].
