Part of the crystal structure of (I

) showing the linking of pairs of C(8)[R $[{_2^2}]$ (6)] chains of rings into a molecular ladder. Atoms marked with an asterisk (*), hash (#), dollar sign ($) or ampersand (&) are at the symmetry positions (1 + x, $[{1 \over 4}]$ , z), (x − 1, $[{1 \over 4}]$ , z), (x − $[{1 \over 2}]$ , $[{1 \over 4}]$ , $[{1 \over 2}]$ − z) and ( $[{1 \over 2}]$ + x, $[{1 \over 4}]$ , $[{1 \over 2}]$ − z), respectively.
