Title: Materials Data on K2TaCuBr6 by Materials Project

Abstract

K2TaCuBr6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. K1+ is bonded to twelve equivalent Br1- atoms to form KBr12 cuboctahedra that share corners with twelve equivalent KBr12 cuboctahedra, faces with six equivalent KBr12 cuboctahedra, faces with four equivalent TaBr6 octahedra, and faces with four equivalent CuBr6 octahedra. All K–Br bond lengths are 3.76 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 KBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ta–Br bond lengths are 2.64 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 KBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cu–Br bond lengths are 2.67 Å. Br1- is bonded in a distorted linear geometry to four equivalent K1+, one Ta3+, and one Cu1+ atom.
