Matrix-isolation IR spectra of halogen–P and halogen–π complexes of phosphines and iodotrifluoroethylene (C <sub>2</sub> F <sub>3</sub> I)
The CC stretching mode of iodotrifluoroethylene (ITFE) serves as a marker for halogen-bonding (XB) interactions in complexes with phosphines. The formation of C-I⋯P XB-complexes becomes evident from a strong red-shift of this marker band. The formation of C-I⋯π bound clusters, which were kinetically trapped in the cryogenic environment, was confirmed by a slightly smaller red-shift of the marker band.
