Abstract
Red single crystals of Pt2(HSO4)2(SO4)2 were obtained by the reaction of elemental platinum with conc. sulfuric acid at 350 °C in sealed glass ampoules. The crystal structure (monoclinic, P21/c, Z = 2, a = 868.6(2), b = 826.2(1), c = 921.8(2) pm, β=116.32(1)°, Rall = 0.0348) shows dumbbell shaped Pt26+ cations which are coordinated by four SO42— and two HSO4— ions. Each of the sulfate ions is attached to another Pt26+ ion yielding layers according to [Pt2(SO4)4/2(HSO4)2/1]. The layers are connected by hydrogen bonds with the OH group of the hydrogensulfate ion as donor and the non‐bonding oxygen atom of the sulfate ion as acceptor.Keywords
