✦ Synopsis

The crystal and molecular structure of potassium P-D-glucopyranose 6sulphate has been determined by direct methods. The sugar ring has the expected 4C1 conformation although the sulphate group causes flattening of the ring. The potassium ion has octahedral co-ordination involving oxygen atoms of five independent /3-D-glucopyranose 6-sulphate molecules. The n.m.r. spectrum of the 6-sulphate in the solid state is consistent with the occurrence of two molecules in the unit cell related by a 2, symmetry axis.
