Materials Data on SrCuSb by Materials Project
SrCuSb crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent Sb3- atoms to form a mixture of edge, face, and corner-sharing SrSb6 octahedra. The corner-sharing octahedral tilt angles are 45°. All Sr–Sb bond lengths are 3.44 Å. Cu1+ is bonded in a trigonal planar geometry to three equivalent Sb3- atoms. All Cu–Sb bond lengths are 2.62 Å. Sb3- is bonded in a 3-coordinate geometry to six equivalent Sr2+ and three equivalent Cu1+ atoms.
