Figure 8
Part of the crystal structure of compound (III) showing the formation of a hydrogen-bonded dimer containing R21(7), R22(10) and R22(16) ring motifs. Hydrogen bonds are shown as dashed lines and, for the sake of clarity, the minor disorder component and the H atoms not involved in the motifs shown have been omitted. The atoms marked with an asterisk (*) are at the symmetry position (−x, 1 − y, 1 − z). |
