摘要：

(Figure Presented) A fresh Pasteur: Reconstruction of Pasteur's 1853 account of peculiar three-component crystals has confirmed the identities of the two crystalline phases as ammonium (+)-bitartrate (central crystal) and a quasiracemate of ammonium (+)-bitartrate/(-)-bimalate (adjoining crystal laths). The quasiracemate contains approximately inversion-related molecular assemblies in which each bitartrate and bimalate component forms a homomeric catemeric motif. © 2008 Wiley-VCH Verlag GmbH & Co.
