| Abstract: | Red single crystals of Gd2Pt2(SO4)4(HSO4)2](HSO4)2 (triclinic,  , Z = 1, a = 844.02(9), b = 908.50(9), c = 939.49(8) pm, α = 107.73(1)°, β = 112.10(1)°, γ = 103.53(1)°) were obtained by the reaction of Gd(NO3)(H2O)7]PtCl6]·4H2O with sulfuric acid at 320 °C in a sealed glass ampoule. In the crystal structure, Pt2 dumbbells are coordinated by four chelating sulfate groups and two monodentate hydrogensulfate ions. Two further HSO4? ions are not bonded to the Pt2 dumbbell. The Gd3+ ions are eightfold coordinated by oxygen atoms. The IR data of Gd2Pt2(SO4)4(HSO4)2](HSO4)2 are typical for these type of compounds. The thermal decomposition of the compound leads to elemental platinum and Gd2O3. |
