The structure of the title compound, showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. Symmetry code: (i) 1 - x, 1 - y, 1 - z; (ii) x + 1, y, z; (iii) -x, 1 - y, 1 - z; (iv) 1 - x, 2 - y, 2 - z; (v) x - 1, y, z.
