Figure 1
Representation of the building units in the crystal structure of compound (1), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level. H atoms are shown as small spheres of arbitrary radius. [Symmetry codes: (i) + x, + y, z; (ii) 1 − x, y, − z; (iii) − x, + y, − z.] |
