Materials Data on SmTiGe by Materials Project

SmTiGe crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sm is bonded in a 5-coordinate geometry to five equivalent Ge atoms. There are four shorter (3.03 Å) and one longer (3.29 Å) Sm–Ge bond lengths. Ti is bonded in a distorted square co-planar geometry to four equivalent Ge atoms. All Ti–Ge bond lengths are 2.78 Å. Ge is bonded in a 9-coordinate geometry to five equivalent Sm and four equivalent Ti atoms.

Materials Data on SmTiGe by Materials Project

SmTiGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sm is bonded in a 5-coordinate geometry to five equivalent Ge atoms. There are four shorter (3.04 Å) and one longer (3.32 Å) Sm–Ge bond lengths. Ti is bonded to four equivalent Ge atoms to form a mixture of distorted edge and corner-sharing TiGe4 cuboctahedra. All Ti–Ge bond lengths are 2.75 Å. Ge is bonded in a 9-coordinate geometry to five equivalent Sm and four equivalent Ti atoms.
