Figure 1 The atom numbering scheme for the centrosymmetric dimeric unit in the title compound with displacement ellipsoids drawn at the 30% probability level. Symmetry codes are: (i) -x + 1, -y, -z + 1; (ii) -x + 1, y - $[{1\over 2}]$ , -z - $[{3\over 2}]$ ; (iii) x, -y + $[{1\over 2}]$ , z + $[{1\over 2}]$ . The second set of hydrogen atoms on the 50% rotationally-disordered methyl groups (C8 and C9) are omitted.
