Abstract
ZrW2O8 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with three equivalent WO4 tetrahedra and corners with three equivalent WO5 trigonal bipyramids. There are three shorter (2.07 Å) and three longer (2.15 Å) Zr–O bond lengths. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to five O2- atoms to form distorted WO5 trigonal bipyramids that share corners with three equivalent ZrO6 octahedra and a cornercorner with one WO4 tetrahedra. The corner-sharing octahedral tilt angles are 24°. There are a spread of W–O bond distances ranging from 1.75–2.34 Å. In the second W6+ site, W6+ is bonded to four O2- atoms to form WO4 tetrahedra that share corners with three equivalent ZrO6 octahedra and a cornercorner with one WO5 trigonal bipyramid. The corner-sharing octahedral tilt angles are 7°. There is one shorter (1.78 Å) and three longer (1.82 Å) W–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one W6+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry tomore »
