Materials Data on Cs2TaCuBr6 by Materials Project
Abstract
Cs2TaCuBr6 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent Br1- atoms to form CsBr12 cuboctahedra that share corners with twelve equivalent CsBr12 cuboctahedra, faces with six equivalent CsBr12 cuboctahedra, faces with four equivalent TaBr6 octahedra, and faces with four equivalent CuBr6 octahedra. All Cs–Br bond lengths are 3.82 Å. Ta3+ is bonded to six equivalent Br1- atoms to form TaBr6 octahedra that share corners with six equivalent CuBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ta–Br bond lengths are 2.66 Å. Cu1+ is bonded to six equivalent Br1- atoms to form CuBr6 octahedra that share corners with six equivalent TaBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cu–Br bond lengths are 2.74 Å. Br1- is bonded in a distorted linear geometry to four equivalent Cs1+, one Ta3+, and one Cu1+ atom.
