, showing the formation of a hydrogen-bonded chain of rings along [010]. For the sake of clarity, the chloroform molecules and H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*), a hash (#) or an ampersand (&) are at the symmetry positions ( $[{1\over 2}]$ − x, − $[{1\over 2}]$ + y, $[{3\over 2}]$ − z), ( $[{1\over 2}]$ − x, $[{1\over 2}]$ + y, $[{3\over 2}]$ − z) and (x, −1 + y, z), respectively.
