Materials Data on Pr3Ge by Materials Project
Pr3Ge crystallizes in the tetragonal P4_2/n space group. The structure is three-dimensional. there are three inequivalent Pr sites. In the first Pr site, Pr is bonded in a 3-coordinate geometry to three equivalent Ge atoms. There are a spread of Pr–Ge bond distances ranging from 3.15–3.28 Å. In the second Pr site, Pr is bonded in a distorted bent 150 degrees geometry to two equivalent Ge atoms. There are one shorter (3.21 Å) and one longer (3.22 Å) Pr–Ge bond lengths. In the third Pr site, Pr is bonded in a distorted see-saw-like geometry to four equivalent Ge atoms. There are a spread of Pr–Ge bond distances ranging from 3.14–3.30 Å. Ge is bonded in a 9-coordinate geometry to nine Pr atoms.
