Tin(II) Oxyhydroxide by X-ray Powder Diffraction

The structure of tin(II) oxyhydroxide, Sn₆O₄(OH)₄, has been refined by Rietveld analysis of X-ray powder diffraction data. Atomic parameters based on the isostructural lead analogue were used in the starting model. The structure was refined in the tetragonal space group P2₁c with a = 7.9268 (4) and c = 9.1025 (5) Å. The title compound forms clusters of Sn₆O₄(OH)₄ with the Sn atoms in distorted tetragonal pyramidal coordination geometries. Each Sn atom is coordinated to two bridging oxide O and two bridging hydroxy O atoms. The JCPDS file number for Sn₆O₄(OH)₄ is 46-1486.
