Title: Materials Data on PrAlGe by Materials Project

Abstract

PrAlGe crystallizes in the tetragonal I4_1md space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded to six Al and six equivalent Ge atoms to form a mixture of edge and face-sharing PrAl6Ge6 cuboctahedra. There are two shorter (3.27 Å) and four longer (3.29 Å) Pr–Al bond lengths. All Pr–Ge bond lengths are 3.28 Å. In the second Pr site, Pr is bonded to six Al and six equivalent Ge atoms to form a mixture of edge and face-sharing PrAl6Ge6 cuboctahedra. There are two shorter (3.27 Å) and four longer (3.29 Å) Pr–Al bond lengths. All Pr–Ge bond lengths are 3.28 Å. There are four inequivalent Al sites. In the first Al site, Al is bonded in a distorted trigonal planar geometry to six Pr and three equivalent Ge atoms. Both Al–Pr bond lengths are 3.27 Å. There are one shorter (2.46 Å) and two longer (2.48 Å) Al–Ge bond lengths. In the second Al site, Al is bonded in a distorted trigonal planar geometry to six Pr and three equivalent Ge atoms.
