Materials Data on Pr2MgGe2 by Materials Project
MgPr2Ge2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Mg is bonded in a square co-planar geometry to four equivalent Ge atoms. All Mg–Ge bond lengths are 3.00 Å. Pr is bonded in a 6-coordinate geometry to six equivalent Ge atoms. There are two shorter (3.08 Å) and four longer (3.19 Å) Pr–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to two equivalent Mg, six equivalent Pr, and one Ge atom. The Ge–Ge bond length is 2.57 Å.
