Synthesis and characterization of bimetallic platinum-thallium compounds

Abstract: The solid bimetallic compounds TtPt(CN)4(ClO4) and TtPt(CN)4(NO3) have been prepared by reactions between tetracyanoplatinate complex [Pt(CN)4]2- and aqueous solutions of Tl(ClO4)3 and Tl(NO3)3, respectively. The elemental analysis (N, C, H, Tl) of the compound has been carried out. The results of the analysis are reasonably consistent with the above compositions of the compounds. The bimetallic compounds have been characterized by IR and Raman spectroscopy as well as X-ray diffraction. IR and Raman spectra of the Tl-Pt compounds confirm presence of the perchlorate and nitrate counter ions in the solid. The presence of a direct Tl-Pt metal-metal bond in the compounds is confirmed by appearance of a strong vibrational band the low frequency region of the vibrational spectra.
