Structure du p-bromobenzoylglycinate de hydroxy-2 cyclopentyle-trans

Crystals of C14HI6BrNO4 are monoclinic, space group C2/c, a = 28.38 (4), b = 9.18 (1), c = 12.349 (2)A, fl = 108.76 (4) °, Z = 8, V = 3046 (8) A 3, dm= 149, d e = 1.51 Mg m-3¢ M r = 342.19. X-ray diffraction intensity data for 1655 observed reflexions were recorded at room temperature with an automated diffractometer. The structure was determined by the heavy-atom method and refined by full-matrix least squares to R = 0.06. The oxygen of the hydroxyl group does not form an intramolecular hydrogen bond with the carbonyl oxygen of the ester function, but is involved in two intermolecular hydrogen bonds. The hydroxyl group acts as a donor through its hydrogen to the oxygen of the peptide group of a second molecule and as an Receptor through the hydrogen of the peptidic nitrogen from a third molecule so building infinite chains.
