Figure 2
The crystal packing of the title compound, with displacement ellipsoids drawn at the 50% probability level. Inversion centres at [0,0,0] and [1/4,1/4,0] with symmetry operations of (−x, −y, −z) and ( − x, − y, −z), respectively, are shown as orange dots. Rotation and screw axes in the [010] direction at (0, y, 1/4) and (1/4, y, 1/4) with symmetry operations of (−x, y, − z) and ( − x, + y, − z), respectively, are shown as purple lines. |
