Figure 2
The independent molecules of (1), showing the atom-numbering scheme and the hard intermolecular hydrogen bonds (dashed lines). Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. [Symmetry codes: (i) −x + 3, −y + 2, −z + 1; (ii) −x, −y + 1, −z + 1.] |
