Part of the crystal structure of (III) showing the formation of a hydrogen-bonded chain of edge-fused rings along [100]. For the sake of clarity, the H atoms bonded to C atoms have been omitted. The atoms marked with an asterisk (*), a hash (#) or a dollar sign ($) are at the symmetry positions (1 - x, 2 - y, 1 - z), (-1 + x, y, z) and (-x, 2 - y, 1 - z), respectively. |
