Preparation and Crystal Structure Determination of Sulphur Dioxide Solvate Crystals with Cetyl- and Dodecyltrimethylammonium Bromide

  • Denitsa Shopova , Robert Dinnebier and Martin Jansen EMAIL logo

Cetyltrimethylammonium bromide (CTAB) and dodecyltrimethylammonium bromide (DTAB) form with sulphur dioxide crystalline solvates which have been characterised by Raman spectroscopy and X-ray powder diffraction (XRPD) at room temperature. In both crystal structures, the fully extended CTAB and DTAB cations are oriented along the a axes, forming infinite parallel stacks along the b axes. Neighbouring stacks form sheets with the bromide anions and the sulphur dioxide molecules acting as chelating agents. Consecutive sheets are flipped and shifted, thus building the three-dimensional crystal structure in a brick-like manner.
