Figure 1
View of a fragment of (I), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. [Symmetry codes: (i) x + 1, y, z; (ii) −x, 1 − y, 1 − z; (iii) 1 − x, 1 − y, 1 − z; (iv) x − 1, y, z; (v) 1 − x, 1 − y, 2 − z; (vi) x, − y, z.] |
