Materials Data on Cs2Ni2(MoO4)3 by Materials Project
Cs2Ni2(MoO4)3 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 12-coordinate geometry to nine O2- atoms. There are a spread of Cs–O bond distances ranging from 3.20–3.29 Å. In the second Cs1+ site, Cs1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are three shorter (3.17 Å) and six longer (3.52 Å) Cs–O bond lengths. Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with four NiO6 octahedra. The corner-sharing octahedra tilt angles range from 8–50°. There is one shorter (1.79 Å) and three longer (1.80 Å) Mo–O bond length. There are two inequivalent Ni2+ sites. In the first Ni2+ site, Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six equivalent MoO4 tetrahedra. There are three shorter (2.08 Å) and three longer (2.09 Å) Ni–O bond lengths. In the second Ni2+ site, Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six equivalent MoO4 tetrahedra. There are three shorter (2.07 Å) and three longer (2.08 Å) Ni–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Cs1+, one Mo6+, and one Ni2+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to two Cs1+, one Mo6+, and one Ni2+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Mo6+, and one Ni2+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cs1+, one Mo6+, and one Ni2+ atom.
