Crystallization of 1,3,5-tris(4-cyanobenzoyl)benzene (1) from EtOAc, MeNO2, and 3-pentanone results in formation of isostructural inclusion complexes mediated by weak hydrogen bonding interactions involving aryl C−H donors and heteroatom acceptors from nitrile, carbonyl, and nitro groups. The solvent guests occupy interlayer channels within a porous triaroylbenzene host network.
