Abstract

K2NaScI6 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 I1- atoms to form KI12 cuboctahedra that share corners with twelve equivalent KI12 cuboctahedra, faces with six equivalent KI12 cuboctahedra, faces with four equivalent NaI6 octahedra, and faces with four equivalent ScI6 octahedra. All K–I bond lengths are 4.26 Å. Na1+ is bonded to six equivalent I1- atoms to form NaI6 octahedra that share corners with six equivalent ScI6 octahedra and faces with eight equivalent KI12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Na–I bond lengths are 3.13 Å. Sc3+ is bonded to six equivalent I1- atoms to form ScI6 octahedra that share corners with six equivalent NaI6 octahedra and faces with eight equivalent KI12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sc–I bond lengths are 2.89 Å. I1- is bonded in a linear geometry to four equivalent K1+, one Na1+, and one Sc3+ atom.
