A new pseudopolymorph of hexa­kis(4‐cyano­phenyl)benzene

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.
