摘要

碘三氟乙烯（ITFE）的C=C拉伸模式是与膦配合物中卤素键（XB）相互作用的标志。C-I•••P xb络合物的形成从该标记带的强红移中可以明显看出。在低温环境中，C-I••••pi键合团簇的形成被动力学捕获，标记带的红移略小，证实了这一点。

Matrix-Isolation IR Spectra of Halogen-P and Halogen-pi Complexes of Phosphines and Iodotrifluoroethylene (C2F3I)

The C=C stretching mode of iodotrifluoroethylene (ITFE) serves as marker for halogen bonding (XB)-interactions in complexes with phosphines. The formation of a C-I•••P XB-complexes becomes evident from a strong red-shift of this marker band. The formation of C-I•••pi bound clusters, which were kinetically trapped in the cryogenic environment, were confirmed by a slightly smaller redshift of the marker band.
