Materials Data on PrZnGa by Materials Project

PrZnGa is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pr is bonded to six equivalent Zn and six equivalent Ga atoms to form a mixture of edge and face-sharing PrZn6Ga6 cuboctahedra. All Pr–Zn bond lengths are 3.25 Å. All Pr–Ga bond lengths are 3.25 Å. Zn is bonded in a 3-coordinate geometry to six equivalent Pr and three equivalent Ga atoms. All Zn–Ga bond lengths are 2.60 Å. Ga is bonded in a 3-coordinate geometry to six equivalent Pr and three equivalent Zn atoms.
