). Displacement ellipsoids are drawn at the 50% probability level. H atoms bound to C atoms have been omitted for clarity, and the remaining H atoms are shown as small spheres of arbitrary radii [symmetry codes: (i) x, y, z; (ii) 1 − x, −y, 1 − z; (iii) $[{3 \over 2}]$ − x, $[y-{1 \over 2}]$ , $[{3 \over 2}]$ − z; (iv) $[x-{1 \over 2}]$ , $[{1 \over 2}]$ − y, $[z-{1 \over 2}]$ ].
