N-(2-Chloro­acet­yl)glycine

The title compound, C₄H₆ClNO₃, crystallizes with two independent mol­ecules (A and B) in the asymmetric unit. In each mol­ecule, there are N—H...O and N—H...Cl hydrogen bonds. Both mol­ecules are relatively planar, with the mean plane of the acetamide [N—C(=O)C] group being inclined to the mean plane of the acetate group [C—C(=O)O] by 9.23 (13)° in mol­ecule A and 6.23 (12)° in mol­ecule B. In the crystal, adjacent mol­ecules are linked by O—H...O hydrogen bonds and weak C—H...O contacts forming –A–A–A– and –B–B–B– parallel chains propagating along the a-axis direction.
