AbstractPolycrystalline potassium hexahydroperoxostannate was prepared by replacement of hydroxo
groups in potassium hexahydroxostannate upon its dissolution in hydrogen peroxide. A comparative study of
the product and the starting hydroxostannate by powder X-ray diffraction analysis, thermogravimetry, and IR,
2H, 39K, and 119Sn NMR, and Mössbauer spectroscopy was carried out. The peroxo compound K2Sn(OOH)6
crystallizes in the hexagonal system with a = 7.264(7) Å, c = 10.168(4) Å. IR, NMR, and Mössbauer spectros-
copy data show that the tin coordination polyhedron in the peroxo compound is an octahedron formed by the
coordinated hydroperoxo groups.
