Abstract
Rietveld refinement of strontium zirconium disilicate, SrZrSi2O7, usin g neutron powder diffraction data [lambda = 2.57167 (3) angstrom, F(00 0) = 252.45, muR = 0.11, 295 contributing reflections] resulted in R(w p) = 2.72%. The structure can be described as alternate layers, contai ning the ZrO6 octahedra and formed by the Si2O7 groups, stacked parall el to [001]. Elongated cages are formed for Sr, which coordinates to g ive distorted SrO8 dodecahedra. The Si2O7 groups are in a nearly eclip sed conformation. The title compound is isostructural with the high-te mperature form of NaFeP2O7.
