Crystal structure of 9,10-bis-((perchloro-phenyl)-ethynyl)anthracene determined from three-dimensional electron diffraction data

The crystal structure of the title compound was determined using electron diffraction data collected in continuous rotation mode. The structure was successfully solved and refined kinematically in the monoclinic space group P2(1)/c, with a Z value of 2 and Z' value of 0.5. Within the crystal structure, the entire molecule is predominantly flat. The molecular packing exhibits a herringbone pattern, distinct from that of the unchlorinated analogue molecule. The largest facet of the crystals, which faces the supporting carbon film, is designated as (011(sic)).
