organic compounds
The title compound, C10H15NO2S, commonly referred to as (1S*,2S*)-(+)-thiomicamine, forms molecular sheets parallel to the a and b axes. Within these sheets, the molecules are connected by strong O—HO and O—HN hydrogen bonds. The methylsulfanyl groups protrude from this network and are interwoven between adjacent sheets.
organic compounds
The title compound, C20H25N2O2+·C4H6ClO2-, was crystallized by evaporation of an acetone solution and this is the first published report describing the structure of a crystal phase for this salt. Quinine is commonly used as a resolving agent for classic resolution. The anion was of interest because it has several desirable properties for absolute configuration studies, viz. strong acidic pKa for salt formation, a somewhat heavy atom for strong diffraction and a known stereocenter.
