Materials Data on K2GeF6 by Materials Project
K2GeF6 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. K1+ is bonded to twelve equivalent F1- atoms to form distorted KF12 cuboctahedra that share corners with six equivalent KF12 cuboctahedra, corners with three equivalent GeF6 octahedra, faces with eight equivalent KF12 cuboctahedra, and faces with three equivalent GeF6 octahedra. The corner-sharing octahedral tilt angles are 18°. There are a spread of K–F bond distances ranging from 2.91–3.04 Å. Ge4+ is bonded to six equivalent F1- atoms to form GeF6 octahedra that share corners with six equivalent KF12 cuboctahedra and faces with six equivalent KF12 cuboctahedra. All Ge–F bond lengths are 1.84 Å. F1- is bonded in a distorted single-bond geometry to four equivalent K1+ and one Ge4+ atom.
