Materials Data on Zn2NiSbO6 by Materials Project

NiZn2SbO6 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Ni3+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with two equivalent NiO6 octahedra and corners with four equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 41–46°. There are a spread of Ni–O bond distances ranging from 1.95–2.15 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Zn–O bond distances ranging from 2.04–2.69 Å. In the second Zn2+ site, Zn2+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Zn–O bond distances ranging from 2.00–2.66 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent SbO6 octahedra and corners with four equivalent NiO6 octahedra. The corner-sharing octahedra tilt angles range from 43–48°. There are a spread of Sb–O bond distances ranging from 1.97–2.09 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Ni3+, two equivalent Zn2+, and one Sb5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ni3+, three Zn2+, and one Sb5+ atom. In the third O2- site, O2- is bonded to two Zn2+ and two equivalent Sb5+ atoms to form distorted OZn2Sb2 tetrahedra that share corners with two equivalent OZn2Sb2 tetrahedra and corners with two equivalent OZn2Ni2 trigonal pyramids. In the fourth O2- site, O2- is bonded to two equivalent Ni3+ and two Zn2+ atoms to form distorted OZn2Ni2 trigonal pyramids that share corners with two equivalent OZn2Sb2 tetrahedra and corners with two equivalent OZn2Ni2 trigonal pyramids.
