Figure 17
Part of the crystal structure of compound (VI) showing the formation of the R44(18) ring which links the (100) sheets. Hydrogen bonds are drawn as dashed lines and, for the sake of clarity, the unit-cell outline and the H atoms which are bonded to the C atoms not involved in the motif shown have been omitted. The atoms marked with an asterisk (*) are at the symmetry position (1 − x, 2 − y, 1 − z). |
