Materials Data on Sr(Sb3Ru)4 by Materials Project

Sr(RuSb3)4 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Sr2+ is bonded to twelve equivalent Sb1- atoms to form SrSb12 cuboctahedra that share faces with eight equivalent RuSb6 octahedra. All Sr–Sb bond lengths are 3.56 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 SrSb12 cuboctahedra. The corner-sharing octahedral tilt angles are 55°. All Ru–Sb bond lengths are 2.65 Å. Sb1- is bonded in a 2-coordinate geometry to one Sr2+, two equivalent Ru+2.50+, and two equivalent Sb1- atoms. There are one shorter (2.97 Å) and one longer (3.00 Å) Sb–Sb bond lengths.
