Infrared spectra of complexes of aniline with metal (II) halides

Abstract

The infrared spectra of aniline complexes with halides of divalent platinum, palladium, copper, nickel, zinc, cadmium, cobalt and manganese are reported in the 4000-280 cm −1 region. With the exception of cadmium chloride, these complexes are of the type dihalobis(aniline) metal (II). Deuteration of the amino group aided in the assignment of the fundamental NH 2 modes. The strongest absorptions are those associated with the NH 2 wagging vibrations. A number of metal-to-chlorine stretching vibration frequencies, below 335 cm −1, have been assigned.
