Materials Data on K2ScHgBr6 by Materials Project
K2ScHgBr6 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 ScBr6 octahedra, and faces with four equivalent HgBr6 octahedra. All K–Br bond lengths are 4.02 Å. Sc2+ is bonded to six equivalent Br1- atoms to form ScBr6 octahedra that share corners with six equivalent HgBr6 octahedra and faces with eight equivalent KBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sc–Br bond lengths are 2.66 Å. Hg2+ is bonded to six equivalent Br1- atoms to form HgBr6 octahedra that share corners with six equivalent ScBr6 octahedra and faces with eight equivalent KBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Hg–Br bond lengths are 3.02 Å. Br1- is bonded in a distorted linear geometry to four equivalent K1+, one Sc2+, and one Hg2+ atom.
