The crystal structure of 1,2,3,4,6-penta-<i>O</i>-acetyl-<i>β</i>-<scp>d</scp>-glucopyranose¹

The crystal structure of the title compound (1) has been determined [space group P212121, a = 5.747(3), b = 14.182(5), c = 24.480(5) Å, Z = 4] and refined to R0.087 for 2059 unique observed reflections. The limited accuracy (typical bond length e.s.d.'s 0.008 Å) is associated with a disordered acetyl group at C(6). The endocyclic acetal bond is longer than the exocyclic by 0.018 Å, reversing the pattern observed in the α-isomer (preceding paper).
