Abstract
Crystals of methyl 4,6-dichloro-4,6-dideoxy-α-D-galactopyranoside are orthorhombic, a= 23·12, b= 8·18, c= 5·091 Å, Z= 4, space-group P212121. The structure was determined with Mo-Kα scintillation counter data by use of Sayre relationships, and was refined by least-squares methods. The molecule has the normal chair conformation, and the bond distances and valency angles are similar to those in related compounds. A feature of the molecular packing is a hydrogen-bonding scheme involving the two hydroxy hydrogen atoms.Keywords
