Abstract

The crystal structure of cesium hexahydroperoxostannate Cs ₂Sn(OOH)₆ is presented. The compound was characterized by single crystal and by powder X-ray diffraction, FTIR, ¹¹⁹Sn MAS NMR, and TG-DTA. Cs₂Sn(OOH)₆ crystallizes in the trigonal space group P3 a = 7.5575(4), c = 5.1050(6) ̊, V = 252.51(4) ̊³, Z = 1, R₁ = 0.0120 (I > 2σ(I)), wR₂ = 0.0293 (all data), and comprises cesium cations and slightly distorted octahedral [Sn(OOH)₆]^2- anions lying on the threefold axis. The [Sn(OOH)₆]^2- unit forms 12 interanion hydrogen bonds resulting in anionic chains spread along the c-axis. All six hydroperoxo ligands are crystallographically equivalent; O-O distances are 1.482(2), only slightly longer than the O-O distance in hydrogen peroxide. FTIR and ¹¹⁹Sn MAS NMR reveal the similarity between all alkali hydroperoxostannates.
