Materials Data on K2NaTmCl6 by Materials Project
K2NaTmCl6 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 Cl1- atoms to form KCl12 cuboctahedra that share corners with twelve equivalent KCl12 cuboctahedra, faces with six equivalent KCl12 cuboctahedra, faces with four equivalent NaCl6 octahedra, and faces with four equivalent TmCl6 octahedra. All K–Cl bond lengths are 3.77 Å. Na1+ is bonded to six equivalent Cl1- atoms to form NaCl6 octahedra that share corners with six equivalent TmCl6 octahedra and faces with eight equivalent KCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Na–Cl bond lengths are 2.74 Å. Tm3+ is bonded to six equivalent Cl1- atoms to form TmCl6 octahedra that share corners with six equivalent NaCl6 octahedra and faces with eight equivalent KCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Tm–Cl bond lengths are 2.59 Å. Cl1- is bonded in a distorted linear geometry to four equivalent K1+, one Na1+, and one Tm3+ atom.
