چکیده
The title compound, C4H6ClNO3, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In each mol-ecule, there are N-H⋯O and N-H⋯Cl hydrogen bonds. Both mol-ecules 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 mol-ecule A and 6.23 (12)° in mol-ecule B. In the crystal, adjacent mol-ecules 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.

In the title mol-ecule, C(18)H(23)ClN(3)O(2)P, the P atom is bonded in a distorted tetra-hedral environment. The P=O and N-H groups are syn with respect to each other. The angles at the tertiary N atoms confirm their sp(2) character. In the crystal, pairs of inter-molecular P=O⋯H-N hydrogen bonds form centrosymmetric dimers.
