Figure 1
The contents of the asymmetric unit of (I), showing all atoms with displacement ellipsoids at the 30% probability level. The two phenyl-group orientations [labelled as a and b sets with occupancies of 0.65 (2) and 0.35 (2), respectively] are distinguished by full and dashed bonds. For the sake of clarity, only one set of H atoms on atom C1 is shown (see Comment). |
