Materials Data on Sr(MnSb)2 by Materials Project
Sr(MnSb)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent Sb3- atoms to form SrSb6 octahedra that share corners with twelve equivalent MnSb4 tetrahedra, edges with six equivalent SrSb6 octahedra, and edges with six equivalent MnSb4 tetrahedra. All Sr–Sb bond lengths are 3.38 Å. Mn2+ is bonded to four equivalent Sb3- atoms to form MnSb4 tetrahedra that share corners with six equivalent SrSb6 octahedra, corners with six equivalent MnSb4 tetrahedra, edges with three equivalent SrSb6 octahedra, and edges with three equivalent MnSb4 tetrahedra. The corner-sharing octahedra tilt angles range from 20–51°. There are three shorter (2.77 Å) and one longer (2.78 Å) Mn–Sb bond lengths. Sb3- is bonded to three equivalent Sr2+ and four equivalent Mn2+ atoms to form a mixture of distorted corner and edge-sharing SbSr3Mn4 pentagonal bipyramids.
