Materials Data on SmNiGe3 by Materials Project
SmNiGe3 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Sm is bonded in a 4-coordinate geometry to four equivalent Ni and ten Ge atoms. All Sm–Ni bond lengths are 3.20 Å. There are a spread of Sm–Ge bond distances ranging from 3.11–3.25 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Sm and five Ge atoms. There are one shorter (2.33 Å) and four longer (2.37 Å) Ni–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Sm, two equivalent Ni, and five Ge atoms. There are one shorter (2.49 Å) and four longer (2.93 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Sm, one Ni, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.54 Å. In the third Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Sm, two equivalent Ni, and five Ge atoms. The Ge–Ge bond length is 2.49 Å.
