Halogen bonding driven self-assembly of (E)-1,2-diiodo-1,2-difluoroethene with nitrogen substituted hydrocarbons

(NI)-I-... halogen bondings drive the intermolecular recognition between (E)-1,2-diiodo-1,2-difluoroethene, which work as bidentate electron acceptor, and TMEDA or 4,4'-dipyridyl, which work as bidentate electron donors. The presence of ID infinite chains in both co-crystals has been established through X-ray analyses. (C) 2003 Elsevier Science Ltd. All rights reserved.
