Figure 1
A view of part of the chain stucture in (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 70% probability level and H atoms are shown as small spheres of arbitrary radii. Hydrogen bonds are shown as dashed lines. [Symmetry codes: (i) −x, −y, −z; (ii) 1 − x, −y, −z; (iii) x − 1, y, z; (iv) x + 1, y, z.] |
