Crystal engineering of 5,5-bisdiazo-dipyrromethane with halogen synthons

Zhenming Yin, Wuyan Wang, Miao Du, Xiuguang Wang and Jianhua Guo

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–HN hydrogen bonds. The halogen synthons also provide a significant contribution to the resulting supramolecular motifs.
