The laserhyphen;Raman spectrum of KAg(CN)2is measured in the region 4500ndash;10 cmminus;1, andngr;2, the symmetric silverndash;cyanide stretch, is unambiguously discriminated for the first time. The laserhyphen;Raman spectrum indicates that the Ag(CN)2minus;ion lies on a site ofC2rather thanCisymmetry. The resolution of13C and15N isotopic bands (in natural abundance) in the CN stretching region provides further evidence that metalndash;cyanide attachment is through the carbon atom in this complex. The lowhyphen;frequency region is studied at high resolution, and 10 Ramanhyphen;active lattice modes are resolved.
