Figure 1 ORTEP-3 (Farrugia, 1997) view of (I) with atom numbering scheme. Displacement ellipsoids for non-H atoms are drawn at the 50% probability level. [Symmetry codes: (i) 0.5-x, 1.5-y, −z; (ii) 0.5-x, −0.5 + y, 0.5-z; (iii) 1-x, y, 0.5-z; (iv) 0.5-x, 0.5 + y, 0.5-z; (v) 0.5 + x, 1.5-y, 0.5 + z] |
