Abstract

AbstractRed single crystals of Gd2[Pt2(SO4)4(HSO4)2](HSO4)2 (triclinic, $P{\bar 1}$, 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 Gd2[Pt2(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.
