The optical properties of the tetracyanoplatinates have been under investigation for nearly two centuries. The earliest reports focused on the alkali and alkaline earth metal tetracyanoplatinates. Much later, two classes of lanthanide tetracyanoplatinates were discovered and characterized by their red and yellow colors. The red compounds are formed by the smaller members of the lanthanide series, and the yellow compounds are formed by the larger lanthanides. Detailed spectroscopic investigations have been carried out for both the red and yellow compounds. Only recently has structural data been reported for the lanthanide tetracyanoplatinate system. The structure of the red tetracyanoplatinate, Er2[Pt(CN)4]3•21H2O, was reported and the other red members are believed to be isostructural with this compound. For the yellow lanthanide tetracyanoplatinates of formula Ln2[Pt(CN)4]3•xH2O, structural data has not been given. We will present the structural data for these as well as other novel lanthanide tetracyanoplatinates in this presentation.
