Infra-red Spectra of some Anhydrous Complex Cyanide Acids

Abstract

AN appreciable number of acids derived from metal cyanide complexes are known, and many can be obtained anhydrous. However, very little information is available as to their structures in the solid state. Penneman et al.1 measured the infra-red spectrum of solid anhydrous aurocyanic acid, HAu(CN)2, and reported a single cyanide stretching frequency at 2,146 cm−1 and an Au—C stretch at 399 cm−1. They found no absorption which could be attributed to a hydrogen stretching frequency.
