Perfluorocarbon-hydrocarbon self assembling. Thermal and vibrational analyses of one-dimensional networks formed by ?,?-diiodoperfluoroalkanes with K.2.2. And K.2.2.2

When perfluorocarbon diiodides 1 and hydrocarbon diamines 2,3 are co-crystallised from chloroform a donor-acceptor interaction between the nitrogen atoms of 1 and the iodine atoms of 2, 3 lead to the formation of infinite one-dimensional coordination networks 4 and 5. Thermal and infrared analyses of these adducts are reported. Nitrogen-iodine interaction is proposed as a non-covalent bonding strong enough to drive the formation of co-crystals between fluorocarbon and hydrocarbon derivatives. © 1998 Elsevier Science S.A.
