Materials Data on ZnNiBiP2O9 by Materials Project
NiZnBiP2O9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Ni3+ sites. In the first Ni3+ site, Ni3+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with four PO4 tetrahedra and edges with two equivalent NiO6 octahedra. There are a spread of Ni–O bond distances ranging from 1.96–2.23 Å. In the second Ni3+ site, Ni3+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with four PO4 tetrahedra and edges with two equivalent NiO6 octahedra. There are a spread of Ni–O bond distances ranging from 1.96–2.23 Å. Zn2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Zn–O bond distances ranging from 2.03–2.58 Å. Bi3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Bi–O bond distances ranging from 2.26–2.38 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two NiO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two NiO6 octahedra. The corner-sharing octahedral tilt angles are 54°. There is two shorter (1.55 Å) and two longer (1.56 Å) P–O bond length. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded to two Ni3+, one Zn2+, and one Bi3+ atom to form corner-sharing OZnNi2Bi tetrahedra. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Zn2+, one Bi3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Zn2+, one Bi3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Zn2+, one Bi3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Bi3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Ni3+, one Zn2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one Ni3+, one Zn2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted linear geometry to one Bi3+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to two Ni3+ and one P5+ atom.
