Materials Data on Pr(GeRh)2 by Materials Project
PrRh2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Pr is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Ge atoms. All Pr–Rh bond lengths are 3.38 Å. All Pr–Ge bond lengths are 3.25 Å. Rh is bonded to four equivalent Pr and four equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing RhPr4Ge4 tetrahedra. All Rh–Ge bond lengths are 2.48 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Pr, four equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.65 Å.
