, showing the formation of a hydrogen-bonded ribbon of edge-fused rings parallel to [100]. For clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($) or an ampersand (&) are at the symmetry positions (− $[{1\over 2}]$ + x, $[{3\over 2}]$ − y, 1 − z), ( $[{1\over 2}]$ + x, $[{3\over 2}]$ − y, 1 − z), (1 + x, y, z) and (−1 + x, y, z), respectively.
