Materials Data on DyMn2SiGe by Materials Project

Abstract

DyMn2GeSi crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Dy is bonded in a 8-coordinate geometry to eight equivalent Mn, four equivalent Ge, and four equivalent Si atoms. There are four shorter (3.23 Å) and four longer (3.34 Å) Dy–Mn bond lengths. All Dy–Ge bond lengths are 3.04 Å. All Dy–Si bond lengths are 3.05 Å. Mn is bonded to four equivalent Dy, two equivalent Ge, and two equivalent Si atoms to form a mixture of corner, edge, and face-sharing MnDy4Si2Ge2 tetrahedra. Both Mn–Ge bond lengths are 2.44 Å. Both Mn–Si bond lengths are 2.35 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Dy, four equivalent Mn, and one Si atom. The Ge–Si bond length is 2.53 Å. Si is bonded in a 9-coordinate geometry to four equivalent Dy, four equivalent Mn, and one Ge atom.
