Title: Materials Data on PrMn2SiGe by Materials Project

Abstract

PrMn2GeSi crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Pr is bonded in a 8-coordinate geometry to eight equivalent Mn, four equivalent Ge, and four equivalent Si atoms. There are four shorter (3.32 Å) and four longer (3.41 Å) Pr–Mn bond lengths. All Pr–Ge bond lengths are 3.12 Å. All Pr–Si bond lengths are 3.13 Å. Mn is bonded to four equivalent Pr, two equivalent Ge, and two equivalent Si atoms to form a mixture of edge, face, and corner-sharing MnPr4Si2Ge2 tetrahedra. Both Mn–Ge bond lengths are 2.46 Å. Both Mn–Si bond lengths are 2.37 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Pr, four equivalent Mn, and one Si atom. The Ge–Si bond length is 2.70 Å. Si is bonded in a 9-coordinate geometry to four equivalent Pr, four equivalent Mn, and one Ge atom.
