Figure 2 One of the three sugar units, A, with all its sodium ion contacts and hydrogen bond inter­actions (dashed double lines). The atom numbering scheme is shown; the atoms of the other mol­ecules are numbered correspondingly, with C, O and S atom numbers n+10 and n+20. The water mol­ecules are labelled O31, O32 and O33. Symmetry codes: (i) x − [{1\over 2}], −y + [{1\over 2}], −z + 1; (ii) x + [{1\over 2}], −y + [{3\over 2}], −z + 1; (iii) x + [{1\over 2}], −y + [{1\over 2}], −z + 1; (iv) x − [{1\over 2}], −y + [{3\over 2}], −z + 1; (v) −x, y + [{1\over 2}], −z + [{1\over 2}]; (vi) −x + 1, y − [{1\over 2}], −z + [{1\over 2}]; (vii) −x + [{1\over 2}], −y + 1, z − [{1\over 2}]; (ix) −x, y − [{1\over 2}], −z + [{1\over 2}]; (xii) x − 1, y, z; (xiii) x + 1, y, z; (xiv) −x + 1, y + [{1\over 2}], −z + [{1\over 2}]; (xv) −x + [{1\over 2}], −y + 1, z + [{1\over 2}].
