Abstract
In the course of extensive investigations of thiocyanate complexes of different metals, the new Raman bands have been recorded for the Hg(II)-SCN-$H_{2}O$ system, in addition to those due to free SCN ion. The new bands, located at $\sim$$240 cm^{-1}$, $\sim$$717 cm^{-1}$ and $\sim 2120 cm^{-1}$, were assumed as a consequence of Hg(II)-SCN complex formation. To obtain more evidence about the nature of species formed, a quantitative Raman spectral study combined with the mole-ratio method have been undertaken. The results are consistent with the presence of the $Hg(SCN)^{2-}_{4}$ species in solution and $Hg(SCN)_{2}$ in solid. The results were discussed and compared with those obtained $previously^{1,2}$.
