The syntheses of threefold acceptor-substituted 1,3.5-triaminobenzene derivatives 2 - 6 and their crystal structure analyses are described. As accepters, nitro, trifluoromethylsulfone, and alkylsulfone groups are employed. The combination of hydrogen bonding, arene...arene and F ... F contacts leads to remarkably similar solid-state layer structures for sterically quite dissimilar molecules.
