(a) Unit-cell packing in the monoclinic form of (III), viewed approximately down [100]. Displacement ellipsoids are drawn at the 50% probability level and all H atoms have been omitted for clarity. (b) Unit-cell packing in the orthorhombic form of (III), viewed approximately down [010]. Displacement ellipsoids are drawn at the 30% probability level and all H atoms have been omitted for clarity [redrawn from Bandoli et al. (1992)]. |
