- Description: A series of amine complexes has been prepared by reaction of zinc chloride and mercuric chloride with primary aromatic amines. A detailed assignment of the bands in the infra-red spectra of the complexes in the range 4000-625 cm [superscript]-1 is presented. The symmetric and asymmetric N-H stretching frequencies follow the relationship v(sym) = 345.5+ 0.876v(asym). The C-N stretching frequencies exhibit a linear relationship with the Hammett α-functions for the m- and p-substituted amines.

- Description: We have examined the infrared spectra of thirty-seven complexes derived from the reaction of zinc chloride, mercuric chloride and cadmium chloride, bromide and iodide with several primary aromatic amines. The object of the study was to ascertain whether the frequency data would shed light on the mechanisms of metal-donor atom bonding and electron shifts within the molecules and, in the case of the cadmium complexes, in order to obtain evidence for the transmission of electronic effects through a cadmium atom.

- Description: A series of novel cadmium complexes has been synthesized from the reaction of cadmium chloride, bromide and iodide with primary aromatic amines. The complexes are either mononuclear or polynuclear according to the nature of the halide and amine employed. A possible mechanism for their formation is proposed. The N - H stretching and bending frequencies are linearly related to the electronegativity of the co-ordinated halogen, indicating that the electron withdrawing capacity of the halogen is transmitted through the cadmium atom.
