The material structure described by USnI6 is Upper Bainite-derived structured and crystallizes in the trigonal P-31c space group. U(1) is bonded to six equivalent I(1) atoms to form UI6 octahedra that share corners with six equivalent Sn(1)I6 octahedra. The corner-sharing octahedral tilt angles are 50°. Sn(1) is bonded to six equivalent I(1) atoms to form SnI6 octahedra that share corners with six equivalent U(1)I6 octahedra. The corner-sharing octahedral tilt angles are 50°. I(1) is bonded in a bent 120 degrees geometry to one U(1) and one Sn(1) atom. is represented by the CIF file [CIF]
