Figure 2
Molecular packing and intermolecular interactions of the four title camphor derivatives, viz. (a) (1), (b) (2), (c) (3) and (d) (4). Stereoviews are down the hydrogen-bond-connected molecular columns (parallel to the b axis) to show the interactions that interconnect the columns. The small circles represent the H atoms involved in intermolecular contacts listed in Table 2. All other H atoms have been omitted for clarity. The intermolecular contacts are shown by the small-diameter dotted lines. |
