Using EXAFS and vibrational spectroscopy a tightly bound solvation shell of H2PtCl6 in DMSO and water solutions is established. The shell contains H3O+, H5O2+ and DMSO molecules, depending on the solvent type. EXAFS suggests
O-atoms of the shell are located at a distance of 3.7-4.4 Å from Pt. Complexes' structure was studied in wide concentration range DMSO and water solutions. The complexes are mononuclear and unhydrolyzed. Combining via the shell is possible
