INFRARED SPECTRA OF SILVER-AMMINE COMPLEXES

The infrared absorption spectra of crystalline bis (diamminesilver) sulfate, diamminesilver nitrate, and their deuterium analogs have been measured in the region from 3500 to 30 cm-1. The spectra have been interpreted in terms of group theoretical predictions of the absorption characteristics of the complex cations and the anions, based on crystallographic considerations. The symmetric and asymmetric silver-nitrogen stretching bands were observed near 380 and 460 cm-1, respectively, and the stretching force constant, calculated on the basis of a simple valence force field, is about 1.65 mdyn/Å. © 1969, American Chemical Society.
