Materials Data on EuSiNi2Ge by Materials Project
EuNi2GeSi crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to eight equivalent Ni, four equivalent Ge, and four equivalent Si atoms. There are four shorter (3.17 Å) and four longer (3.26 Å) Eu–Ni bond lengths. All Eu–Ge bond lengths are 3.16 Å. All Eu–Si bond lengths are 3.18 Å. Ni is bonded in a 12-coordinate geometry to four equivalent Eu, two equivalent Ge, and two equivalent Si atoms. Both Ni–Ge bond lengths are 2.39 Å. Both Ni–Si bond lengths are 2.31 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Eu, four equivalent Ni, and one Si atom. The Ge–Si bond length is 2.63 Å. Si is bonded in a 9-coordinate geometry to four equivalent Eu, four equivalent Ni, and one Ge atom.
