Abstract
The Raman spectra of solutions containing cuprous, argentous, and mercuric ions together with cyanide ions indicate the presence of the di-, tri-, and tetra-coordinated complexes. The spectra from solutions containing zinc and cadmium ions, respectively, with cyanide ions could be investigated in concentrations where only the tetra-coordinated complex is observed.
