The compound described by Sm2InGe2 crystallizes in the tetragonal P4/mbm space group. Sm(1) is bonded in a 10-coordinate geometry to four equivalent In(1) and six equivalent Ge(1) atoms. In(1) is bonded to eight equivalent Sm(1) and four equivalent Ge(1) atoms to form a mixture of face and corner-sharing InSm8Ge4 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), two equivalent In(1), and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
