The compound described by Sm2FeGe4 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 11-coordinate geometry to one Fe(1), two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(2) atoms. In the second Sm site, Sm(2) is bonded in a 14-coordinate geometry to four equivalent Fe(1), two equivalent Ge(2), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(1) atoms. Fe(1) is bonded in a 5-coordinate geometry to one Sm(1), four equivalent Sm(2), one Ge(1), two equivalent Ge(3), and two equivalent Ge(4) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Sm(1), four equivalent Sm(2), one Fe(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent Sm(2), four equivalent Sm(1), and two equivalent Ge(1) atoms. In the third Ge site, Ge(3) is bonded in a 6-coordinate geometry to two equivalent Sm(1), two equivalent Sm(2), and two equivalent Fe(1) atoms. In the fourth Ge site, Ge(4) is bonded in a 6-coordinate geometry to two equivalent Sm(1), two equivalent Sm(2), and two equivalent Fe(1) atoms. is represented by the CIF card [CIF]
