摘要

Based on preceeding investigations on the crystallization and structures of 13 inclusion compounds with a variety of guest molecules in the host matrix of N, N'-Ditosyl-p-phenylenediamine, the crystal structures of N, N'-Di(4-nitro-benzosulfuryl)-p-phenylenediamine and the five hydrogen bond acceptor molecules cyclopentanone, cyclohexanone, tetrahydrofurane, N, N-dimethylformamide, and pyridine are reported and discussed. In all of the host/guest aggregates formed, the planes of the (4-nitro) phenyl substituents are more strongly twisted out of the p-phenylene plane than in the guest-free host crystal structure, substantiating the importance of optimum conformation of the sulfonamide backbone. The dominant interactions, however, are the hydrogen bonds from the donor host to the acceptor guest, which prevent the usual formation the hydrogen bonds from the donor host to the acceptor guest, which prevent the usual formation of (sulfonamide...sulfonamide) hydrogen bond motifs in the host lattice. A pecularity is found in the 4:1 stochiometry of the pyridine inclusion compound of N, N'-di (4-nitro-benzosulfuryl)-p-phenylenediamine.
