Part of the crystal structure of (I

) showing the formation of a chain of fused rings along [001]. Atoms marked with an asterisk (*), hash (#), dollar sign ($) or ampersand (&) are at the symmetry positions (−x, y, $[{1 \over 2}]$ − z), (−x, 1 − y, 1 − z), (x, 1 − y, z − $[{1 \over 2}]$ ) and (x, 1 − y, $[{1 \over 2}]$ + z), respectively.
