Materials Data on Ba(Sb3Ru)4 by Materials Project

BaRu4Sb12 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Ba2+ is bonded to twelve equivalent Sb1- atoms to form BaSb12 cuboctahedra that share faces with eight equivalent RuSb6 octahedra. All Ba–Sb bond lengths are 3.58 Å. Ru+2.50+ is bonded to six equivalent Sb1- atoms to form RuSb6 octahedra that share corners with six equivalent RuSb6 octahedra and faces with two equivalent BaSb12 cuboctahedra. The corner-sharing octahedral tilt angles are 55°. All Ru–Sb bond lengths are 2.66 Å. Sb1- is bonded in a 2-coordinate geometry to one Ba2+, two equivalent Ru+2.50+, and two equivalent Sb1- atoms. There are one shorter (2.95 Å) and one longer (3.03 Å) Sb–Sb bond lengths.

Materials Data on Ba(SbRu)2 by Materials Project

Ba(RuSb)2 is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a body-centered cubic geometry to eight equivalent Sb3- atoms. All Ba–Sb bond lengths are 3.64 Å. Ru2+ is bonded to four equivalent Sb3- atoms to form a mixture of edge and corner-sharing RuSb4 tetrahedra. All Ru–Sb bond lengths are 2.60 Å. Sb3- is bonded in a 8-coordinate geometry to four equivalent Ba2+ and four equivalent Ru2+ atoms.
