Figure 1
A view of the molecular structure of the asymmetric unit of the title compound (I), with atom labelling. Displacement ellipsoids are drawn at the 50% probability level. For this figure, the symmetry codes are: (i) x − , −y, z; (ii) −x, −y + 1, z + ; (iii) −x, −y + 1, z − ; (iv) x + , −y, z. |
