Materials Data on SrSbAu by Materials Project
SrAuSb crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent Au1+ and five equivalent Sb3- atoms to form a mixture of distorted face and corner-sharing SrSb5Au6 trigonal bipyramids. All Sr–Au bond lengths are 3.55 Å. There are three shorter (3.16 Å) and two longer (3.26 Å) Sr–Sb bond lengths. Au1+ is bonded in a 8-coordinate geometry to six equivalent Sr2+ and two equivalent Au1+ atoms. Both Au–Au bond lengths are 3.26 Å. Sb3- is bonded to five equivalent Sr2+ atoms to form a mixture of edge and corner-sharing SbSr5 trigonal bipyramids.
