Crystal Engineering with Symmetrical Threefold Acceptor-Substituted Triaminobenzenes

Is it possible to identify molecular architectures that allow prediction of crystal structures? Can the factors that determine these structures be identified? To answer these questions, analogues of 1, which forms layer structures, were synthesized in which some or all of the nitro groups were replaced with sulfonyl acceptors. Surprisingly, the expected drastic change in the conformational and/or crystallographic behavior was not observed.
