Materials Data on Pr(CoGe)2 by Materials Project
Pr(CoGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Pr is bonded in a 8-coordinate geometry to eight equivalent Co and eight equivalent Ge atoms. All Pr–Co bond lengths are 3.29 Å. All Pr–Ge bond lengths are 3.17 Å. Co is bonded to four equivalent Pr and four equivalent Ge atoms to form a mixture of distorted edge, face, and corner-sharing CoPr4Ge4 tetrahedra. All Co–Ge bond lengths are 2.36 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Pr, four equivalent Co, and one Ge atom. The Ge–Ge bond length is 2.76 Å.
