Figure 2
The molecular structures of the disordered components of the title compound in monoclinic polymorph (II)

, showing the atom-labelling scheme: (a) the major component, (b) the minor component and (c) the two components together. In parts (a) and (b), the displacement ellipsoids are drawn at the 30% probability level, and in part (c), most of the atom labels have been omitted for the sake of clarity. In each part, atoms marked with the suffix `a' are at the symmetry position (−x + $[{1\over 2}]$ , −y + $[{1\over 2}]$ , −z + 1).
