ORTEP-3 (Farrugia, 1997) diagram of (I) showing 25% probability displacement ellipsoids. C atoms are shown with ellipsoids with only enveloping ellipses and the remaining atoms are shown with ellipsoids with octant shading. Only the asymmetric unit is labelled and H atoms have been omitted for clarity [symmetry code: (i) −x, y, −z + ]. |
