Materials Data on Yb(Sb3Os)4 by Materials Project
YbOs4Sb12 is Upper Bainite-derived structured and crystallizes in the cubic Im-3 space group. The structure is three-dimensional and consists of two ytterbium molecules and one OsSb3 framework. In the OsSb3 framework, Os2- is bonded to six equivalent Sb+0.50+ atoms to form corner-sharing OsSb6 octahedra. The corner-sharing octahedral tilt angles are 54°. All Os–Sb bond lengths are 2.65 Å. Sb+0.50+ is bonded in a bent 120 degrees geometry to two equivalent Os2- atoms.
