title: A new pseudopolymorph of hexakis(4-cyanophenyl)benzene.
abstract: The title compound (systematic name: benzene-4,4',4'',4''',4'''',4'''''-hexaylhexabenzonitrile dichloromethane disolvate), C48H24N6.2CH2Cl2, crystallizes as an inclusion compound during the slow diffusion of methanol into a solution of hexakis(4-cyanophenyl)benzene in CH2Cl2. The hexakis(4-cyanophenyl)benzene molecule lies on an axis of twofold rotation in the space group Pbcn. Weak C-H...N interactions between hexakis(4-cyanophenyl)benzene molecules define an open network with space for including guests. The resulting structure is a new pseudopolymorph of hexakis(4-cyanophenyl)benzene. The eight known pseudopolymorphs have few shared architectural features, in part because none of the intermolecular interactions that are present plays a dominant role or forces neighboring molecules to assume particular relative orientations.
