Figure 1
A view of the molecular structure of (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level. Atoms of the asymmetric unit and O atoms completing the interaction spheres around the Na atoms are shown. [Symmetry codes: (i) x, y − 1, z; (ii) 1 − x, 2 − y, 1 − z; (iii) 2 − x, 1 − y, −z; (iv) 1 − x, 2 − y, −z; (v) 2 − x, 1 − y, 1 − z.] Methylene H atoms have been omitted for clarity. The two intramolecular hydrogen bonds are indicated by dashed lines. |
