Materials Data on UGeI6 by Materials Project
UGeI6 is Upper Bainite-derived structured and crystallizes in the trigonal P-31c space group. The structure is three-dimensional. U4+ is bonded to six equivalent I1- atoms to form UI6 octahedra that share corners with six equivalent GeI6 octahedra. The corner-sharing octahedral tilt angles are 49°. All U–I bond lengths are 3.02 Å. Ge2+ is bonded to six equivalent I1- atoms to form GeI6 octahedra that share corners with six equivalent UI6 octahedra. The corner-sharing octahedral tilt angles are 49°. All Ge–I bond lengths are 3.06 Å. I1- is bonded in a distorted bent 120 degrees geometry to one U4+ and one Ge2+ atom.
