IR AND 13C-NMR SPECTRAL PROPERTIES OF THE LAYERED INCLUSION COMPOUND BIS(THIOUREA)HEXAMETHYLENETETRAMINE

The structure of the 1: 2 adduct of hexamethylenetetramine and thiourea was reanalyzed reinterpreting X-ray diffraction data and providing additional IR and NMR spectroscopic features. The product is thus described as supramolecular commensurate host-guest complex corresponding to the intercalation...
