Abstract

Chlorine, bromine and iodine substituted derivatives of 5,5′-bisdiazo-dipyrromethane have been synthesized and their crystal structures were studied by X-ray crystallography. In the three structures, the 5,5′-bisdiazo-dipyrromethanes form interlocked dimers through quadruple N–H⋯N hydrogen bonds. The halogen⋯π synthons also provide a significant contribution to the resulting supramolecular motifs.
