Sucrose: Precise Determination of Crystal and Molecular Structure by Neutron Diffraction

Abstract

This analysis provides the first precise molecular parameters for sucrose. All hydrogen atoms are included. Carbon-carbon distances are 1.51 1.53 A; carbon-oxygen 1.40 to 1.44 A; carbon-hydrogen 1.08 to 1.11 A; oxygen-hydrogen 0.94 to 0.99 A. The furanose ring conformation differs from that in sucrose sodium bromide dihydrate. Hydrogen bonds (two of them intramolecular) utilize every hydroxyl group except one.
