Abstract
The crystal structures of four crystal forms of rifaximin, named a, b, d and e, have been elucidated by a combination of single crystal and powder diffraction experiments with synchrotron and X-ray sources. The crystal structures of the d and e forms have been determined from powder diffraction data alone. Hot stage microscopy has also been of paramount importance in the understanding of the b -> a conversion process.File in questo prodotto:
