Materials Data on Ca3Ni2(WO6)2 by Materials Project
Abstract
Ca3Ni2(WO6)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 octahedra that share corners with two equivalent WO6 octahedra, corners with four equivalent NiO6 octahedra, an edgeedge with one CaO6 octahedra, an edgeedge with one NiO6 octahedra, and edges with two equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 36–50°. There are a spread of Ca–O bond distances ranging from 2.30–2.49 Å. In the second Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 octahedra that share corners with two equivalent WO6 octahedra, corners with four equivalent CaO6 octahedra, corners with four equivalent NiO6 octahedra, an edgeedge with one NiO6 octahedra, and edges with two equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 36–69°. There are a spread of Ca–O bond distances ranging from 2.24–2.47 Å. In the third Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 octahedra that share corners with two equivalent WO6 octahedra, corners with four equivalent CaO6 octahedra, corners with four equivalent NiO6 octahedra, an edgeedge with one CaO6more »
