摘要：

The solid state arrangements of extended thiophene derivatives associating pentafluorophenyl units linked via azomethine bonds are analyzed in terms of intermolecular interactions involving hydrogen and halogen bonds and pi-pi(F) interactions. It is shown that in the presence of the shortest conjugated systems, the structure is driven by F...F type II contacts giving orthogonal disposition while the lengthening of the conjugated backbone favors parallel arrangements via pi-pi(F) interactions.
