Materials Data on CuAgF3 by Materials Project

AgCuF3 is (Cubic) Perovskite structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. 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 CuF6 octahedra. There are a spread of Ag–F bond distances ranging from 2.80–2.87 Å. Cu2+ is bonded to six F1- atoms to form CuF6 octahedra that share corners with six equivalent CuF6 octahedra and faces with eight equivalent AgF12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. There are four shorter (2.00 Å) and two longer (2.01 Å) Cu–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted linear geometry to four equivalent Ag1+ and two equivalent Cu2+ atoms. In the second F1- site, F1- is bonded in a distorted linear geometry to four equivalent Ag1+ and two equivalent Cu2+ atoms.
