Materials Data on SrCuBi by Materials Project
BiSrCu is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sr is bonded to six equivalent Cu and six equivalent Bi atoms to form a mixture of edge and face-sharing SrCu6Bi6 cuboctahedra. All Sr–Cu bond lengths are 3.51 Å. All Sr–Bi bond lengths are 3.51 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Sr and three equivalent Bi atoms. All Cu–Bi bond lengths are 2.70 Å. Bi is bonded in a 9-coordinate geometry to six equivalent Sr and three equivalent Cu atoms.
