Materials Data on SrZnPb by Materials Project

SrZnPb 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 Zn and six equivalent Pb atoms to form a mixture of edge and face-sharing SrZn6Pb6 cuboctahedra. All Sr–Zn bond lengths are 3.58 Å. All Sr–Pb bond lengths are 3.58 Å. Zn is bonded in a distorted trigonal planar geometry to six equivalent Sr and three equivalent Pb atoms. All Zn–Pb bond lengths are 2.77 Å. Pb is bonded in a distorted trigonal planar geometry to six equivalent Sr and three equivalent Zn atoms.
