Materials Data on NiAgF3 by Materials Project
AgNiF3 is (Cubic) Perovskite structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Ni2+ is bonded to six F1- atoms to form NiF6 octahedra that share corners with six equivalent NiF6 octahedra and faces with eight equivalent AgF12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–2°. All Ni–F bond lengths are 2.00 Å. Ag1+ is bonded to twelve F1- atoms to form AgF12 cuboctahedra that share corners with twelve equivalent AgF12 cuboctahedra, faces with six equivalent AgF12 cuboctahedra, and faces with eight equivalent NiF6 octahedra. There are a spread of Ag–F bond distances ranging from 2.78–2.89 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted linear geometry to two equivalent Ni2+ and four equivalent Ag1+ atoms. In the second F1- site, F1- is bonded in a distorted linear geometry to two equivalent Ni2+ and four equivalent Ag1+ atoms. In the third F1- site, F1- is bonded in a distorted linear geometry to two equivalent Ni2+ and four equivalent Ag1+ atoms.
