Figure 1
(a) A view of the coordination of the Na+ ion showing 20% probability displacement ellipsoids and the atom labelling. Only one component of the disordered C32–C34 ring is displayed. (b) A view of one complete anion, formed by the O11⋯HO32i and O12⋯HO22ii hydrogen bonds, and of the four Na+ cations to which it bonds. These cations are part of a chain running parallel to the b axis. [Symmetry codes: (i) ½ − x, ½ + y, − z; (ii) ½ − x, y − ½, − z; (iii) x, −1 + y, z.] |
