Materials Data on Ba6Ru3(ClO6)2 by Materials Project

Abstract

Ba6Ru3Cl2O12 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 7-coordinate geometry to three equivalent O2- and four equivalent Cl1- atoms. All Ba–O bond lengths are 2.57 Å. There are one shorter (3.22 Å) and three longer (3.53 Å) Ba–Cl bond lengths. In the second Ba2+ site, Ba2+ is bonded in a 10-coordinate geometry to nine O2- and one Cl1- atom. There are three shorter (2.69 Å) and six longer (2.99 Å) Ba–O bond lengths. The Ba–Cl bond length is 3.15 Å. In the third Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, corners with three equivalent RuO6 octahedra, faces with three equivalent BaO12 cuboctahedra, and faces with six RuO6 octahedra. The corner-sharing octahedral tilt angles are 12°. There are a spread of Ba–O bond distances ranging from 2.96–3.07 Å. There are two inequivalent Ru+4.67+ sites. In the first Ru+4.67+ site, Ru+4.67+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with three equivalent BaO12 cuboctahedra, faces with three equivalent BaO12 cuboctahedra, and a faceface with one RuO6 octahedra. There are three shorter (1.91 Å) and three longer (2.10 Å) Ru–O bond lengths. In the second Ru+4.67+ site, Ru+4.67+ is bonded to six equivalent O2- atoms to form RuO6 octahedra that share faces with six equivalent BaO12 cuboctahedra and faces with two equivalent RuO6 octahedra. All Ru–O bond lengths are 2.02 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to four Ba2+ and one Ru+4.67+ atom. In the second O2- site, O2- is bonded in a 6-coordinate geometry to four Ba2+ and two Ru+4.67+ atoms. Cl1- is bonded to five Ba2+ atoms to form a mixture of distorted edge and corner-sharing ClBa5 trigonal bipyramids.
