Ampicillin Trihydrate from Synchrotron Powder Diffraction Data
The crystal structure of ampicillin trihydrate {l_brace}systematic name: 6-[D(-)-{alpha}-aminophenylacetamido]penicillanic acid trihydrate{r_brace}, C{sub 16}H{sub 19}N{sub 3}O{sub 4}S{center_dot}3H{sub 2}O, a broad-spectrum {beta}-lactam antibiotic of the aminopenicillin type, has been determined from synchrotron X-ray powder diffraction data. The three water molecules form an infinite hydrogen-bonded chain through the crystal structure, with hydrogen bonds to the NH{sub 3}{sup +}, COO{sup -}, C{double_bond}O and NH groups of the ampicillin molecules.
