Materials Data on Ni3(AsO4)4 by Materials Project
Abstract
Ni3(AsO4)4 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Ni3(AsO4)4 sheet oriented in the (-1, 0, 2) direction. there are two inequivalent Ni4+ sites. In the first Ni4+ site, Ni4+ is bonded to five O2- atoms to form distorted NiO5 trigonal bipyramids that share corners with five AsO4 tetrahedra. There are a spread of Ni–O bond distances ranging from 1.92–2.26 Å. In the second Ni4+ site, Ni4+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.82 Å) and two longer (1.89 Å) Ni–O bond length. There are two inequivalent As5+ sites. In the first As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with three equivalent NiO5 trigonal bipyramids. There are a spread of As–O bond distances ranging from 1.71–1.75 Å. In the second As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with two equivalent NiO5 trigonal bipyramids. There are a spread of As–O bond distances ranging from 1.70–1.77 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry tomore »
