Part of the crystal structure of compound (III)

, showing the formation of a hydrogen-bonded C(6) chain along [1 $[\overline{1}]$ 0]. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions ( $[{1\over 2}]$ + x, − $[{1\over 2}]$ + y, z) and (− $[{1\over 2}]$ + x, − $[{1\over 2}]$ + y, z), respectively.
