Abstract

Sr3W2O9 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to five O2- atoms to form distorted SrO5 trigonal bipyramids that share corners with four WO4 tetrahedra, a cornercorner with one SrO5 trigonal bipyramid, and edges with two equivalent SrO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.35–2.62 Å. In the second Sr2+ site, Sr2+ is bonded to six O2- atoms to form SrO6 octahedra that share corners with two equivalent SrO6 octahedra, corners with four WO4 tetrahedra, and edges with four SrO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 62°. There are a spread of Sr–O bond distances ranging from 2.37–2.65 Å. In the third Sr2+ site, Sr2+ is bonded to five O2- atoms to form distorted SrO5 trigonal bipyramids that share corners with four WO4 tetrahedra, a cornercorner with one SrO5 trigonal bipyramid, and edges with two equivalent SrO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.35–2.63 Å. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to four O2- atoms to form WO4 tetrahedra that share cornersmore »« less
