A fragment of the molecular structure of the title compound showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level [symmetry codes: (i) x, −y, 1 − z; (ii) −x, −y, z; (iii) x, −y, z; (iv) −x, y, z; (v) −1 + x, −y, z; (vi) −1 + x, −y, −z; (vii) 1 − x, y, 1 + z; (viii) 1 − x, y, 1 − z]. |
