Materials Data on Ba2LuSbO6 by Materials Project
Lu(BaO3)2Sb is alpha Rhenium trioxide-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional and consists of two antimony molecules, two lutetium molecules, and one BaO3 framework. In the BaO3 framework, Ba2+ is bonded to six O2- atoms to form corner-sharing BaO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.35 Å) and two longer (2.36 Å) Ba–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent Ba2+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two equivalent Ba2+ atoms. In the third O2- site, O2- is bonded in a linear geometry to two equivalent Ba2+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to two equivalent Ba2+ atoms. Both O–Ba bond lengths are 2.35 Å.
