资源简介：
Rb2HgGaBr6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent Br1- atoms to form RbBr12 cuboctahedra that share corners with twelve equivalent RbBr12 cuboctahedra, faces with six equivalent RbBr12 cuboctahedra, faces with four equivalent HgBr6 octahedra, and faces with four equivalent GaBr6 octahedra. All Rb–Br bond lengths are 3.92 Å. Hg1+ is bonded to six equivalent Br1- atoms to form HgBr6 octahedra that share corners with six equivalent GaBr6 octahedra and faces with eight equivalent RbBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Hg–Br bond lengths are 2.92 Å. Ga3+ is bonded to six equivalent Br1- atoms to form GaBr6 octahedra that share corners with six equivalent HgBr6 octahedra and faces with eight equivalent RbBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ga–Br bond lengths are 2.63 Å. Br1- is bonded in a 2-coordinate geometry to four equivalent Rb1+, one Hg1+, and one Ga3+ atom.
