Materials Data on Eu(Sb3Os)4 by Materials Project
Eu(OsSb3)4 is Upper Bainite-derived structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional and consists of three europium molecules and one OsSb3 framework. In the OsSb3 framework, there are two inequivalent Os2- sites. In the first Os2- site, Os2- is bonded to six Sb+0.50+ atoms to form corner-sharing OsSb6 octahedra. The corner-sharing octahedral tilt angles are 55°. All Os–Sb bond lengths are 2.72 Å. In the second Os2- site, Os2- is bonded to six equivalent Sb+0.50+ atoms to form corner-sharing OsSb6 octahedra. The corner-sharing octahedral tilt angles are 55°. All Os–Sb bond lengths are 2.72 Å. There are two inequivalent Sb+0.50+ sites. In the first Sb+0.50+ site, Sb+0.50+ is bonded in a bent 120 degrees geometry to two Os2- atoms. In the second Sb+0.50+ site, Sb+0.50+ is bonded in a bent 120 degrees geometry to two equivalent Os2- atoms.
