Materials Data on Cs2HgIrF6 by Materials Project
Cs2IrHgF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent F1- atoms to form distorted CsF12 cuboctahedra that share corners with twelve equivalent CsF12 cuboctahedra, faces with six equivalent CsF12 cuboctahedra, faces with four equivalent IrF6 octahedra, and faces with four equivalent HgF6 octahedra. All Cs–F bond lengths are 3.43 Å. Ir3+ is bonded to six equivalent F1- atoms to form IrF6 octahedra that share corners with six equivalent HgF6 octahedra and faces with eight equivalent CsF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ir–F bond lengths are 1.97 Å. Hg1+ is bonded to six equivalent F1- atoms to form HgF6 octahedra that share corners with six equivalent IrF6 octahedra and faces with eight equivalent CsF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Hg–F bond lengths are 2.85 Å. F1- is bonded in a 1-coordinate geometry to four equivalent Cs1+, one Ir3+, and one Hg1+ atom.
