Materials Data on Sm2InGe2 by Materials Project
Sm2InGe2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Sm is bonded in a 6-coordinate geometry to four equivalent In and six equivalent Ge atoms. All Sm–In bond lengths are 3.50 Å. There are two shorter (3.03 Å) and four longer (3.14 Å) Sm–Ge bond lengths. In is bonded to eight equivalent Sm and four equivalent Ge atoms to form a mixture of face and corner-sharing InSm8Ge4 cuboctahedra. All In–Ge bond lengths are 2.99 Å. Ge is bonded in a 9-coordinate geometry to six equivalent Sm, two equivalent In, and one Ge atom. The Ge–Ge bond length is 2.56 Å.
