Figure 1
An ORTEP-3 (Farrugia, 1997) view, showing the asymmetric unit and part of the polymeric unit of (I), with 50% probability displacement ellipsoids. The asymmetric unit atoms, plus symmetry-generated atoms O2A, O2B, O1C and B1B, are labelled. [Symmetry codes: (A) −x + 2, −y, z + 1; (B) x, y, z + 1; (C) −x + 2, −y, z.] |
