, showing the formation of a chain of rings along [101]. For the sake of clarity, only the major conformer is shown, and 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, $[{1\over 2}]$ + z) and (− $[{1\over 2}]$ + x, $[{1\over 2}]$ − y, − $[{1\over 2}]$ + z), respectively.
