Materials Data on PrCuGe by Materials Project
PrCuGe is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Pr is bonded to six equivalent Cu and six equivalent Ge atoms to form a mixture of edge and face-sharing PrCu6Ge6 cuboctahedra. All Pr–Cu bond lengths are 3.21 Å. All Pr–Ge bond lengths are 3.21 Å. Cu is bonded in a 3-coordinate geometry to six equivalent Pr and three equivalent Ge atoms. All Cu–Ge bond lengths are 2.45 Å. Ge is bonded in a 3-coordinate geometry to six equivalent Pr and three equivalent Cu atoms.
