| DESCRIPTION |
Describe 2 different kinds of endless chains based on compds contg oxygen In one series, alpha,omega-diiodoperfluoroalkane molecules alternate with 1,4-
dioxanes. In example shown, the O-I distance is 2.8 angstroem – longer than the av covalent bond between those atoms but shorter than the sum of their van der Waals radii. In the 2nd complex, the researchers report the O atom of hexamethylphosphoramide interacts symmetrically with 2 neighboring I atoms from flanking perfluoroalkyl iodides
