Materials Data on CaZnGe by Materials Project
CaZnGe is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ca is bonded to six equivalent Zn and six equivalent Ge atoms to form a mixture of edge and face-sharing CaZn6Ge6 cuboctahedra. All Ca–Zn bond lengths are 3.23 Å. All Ca–Ge bond lengths are 3.23 Å. Zn is bonded in a distorted trigonal planar geometry to six equivalent Ca and three equivalent Ge atoms. All Zn–Ge bond lengths are 2.49 Å. Ge is bonded in a 3-coordinate geometry to six equivalent Ca and three equivalent Zn atoms.
