Figure 1
A view of the asymmetric unit of (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms have been omitted for clarity [symmetry codes: (i) 2 − x, 1 − y, 1 − z; (ii) x, 1 + y, z; (iii) 2 − x, 2 − y, 1 − z; (iv) 2 − x, 1 − y, −z]. |
