(2S,3R)-2-[(4-Ethyl-2,3-dioxopiperazin-1-yl)carbonyl-amino]-3-hydroxy-butyric acid monohydrate.

ABSTRACT: In the title compound, C(11)H(17)N(3)O(6)·H(2)O, an important building block of the medicine cefbuperazone sodium, the piperazine ring adopts a screw-boat conformation. Inter-molecular O-H?O and intra-molecular N-H?O hydrogen bonds are observed. The water mol-ecule participates as both donor and acceptor in this framework.

(2S)-2-(4-Ethyl-2,3-dioxopiperazine-1-carboxamido)-2-(4-hy-droxy-phen-yl)acetic acid.

Project description:There are two mol-ecules in the asymmetric unit of the title compound, C(15)H(17)N(3)O(6). The 2,3-dioxopiperazine ring adopts a half-chair conformation with torsion angles of -7.6?(4) and 35.1?(4)° in one mol-ecule, and 5.3?(4) and 45.4?(4)° in the other mol-ecule. In the crystal structure, the carb-oxy groups are involved in classical inversion-related O-H?O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further linked by inter-molecular O-H?O and C-H?O hydrogen bonds. Each independent mol-ecule also exhibits an intra-molecular N-H?O hydrogen bond. The H atoms of the carb-oxy groups are disordered over two positions, with refined site-occupancy factors of 0.5.
