Figure 4
Part of the crystal structure of (II ), showing the formation of a [100] chain of spiro-fused R (12) rings. For the sake of clarity, H atoms bonded to C atoms but not involved in the hydrogen-bonding motif shown have been omitted. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (1 + x, y, z) and (x − 1, y, z), respectively. |
