Figure 3
A molecular diagram of (Ib), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level. H atoms have been omitted for clarity. Cg1, Cg2 and Cg3 denote ring centroids. Intramolecular interactions (P⋯O contacts and C—H⋯π bonds) are shown as single dashed lines. The minor component of the disordered ethyl group is shown by double dashed bonds and dashed ellipsoids. |
