Figure 1
Molecular diagrams showing the numbering scheme used, as well as the way in which chains are formed, for compounds (I) (left) and (II) (right). Full ellipsoids denote the independent unit, with full bonds corresponding to the backbone and empty bonds to the solvent molecules. Empty ellipsoids represent the symmetry-generated part of the structure. Displacement ellipsoids are drawn at the 40% probability level. H atoms attached to C atoms have been omitted for clarity. |
