YFeGe2 crystallizes in the orthorhombic Cmcm space group. Y(1) is bonded in a 15-coordinate geometry to five equivalent Fe(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. Fe(1) is bonded in a 5-coordinate geometry to five equivalent Y(1), one Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Y(1), one Fe(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Y(1) and four equivalent Fe(1) atoms.
YFeGe2 crystallizes in the orthorhombic Cmcm space group. Y(1) is bonded in a 15-coordinate geometry to five equivalent Fe(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. There are four shorter (3.29 Å) and one longer (3.37 Å) Y(1)-Fe(1) bond length. There are two shorter (3.13 Å) and two longer (3.21 Å) Y(1)-Ge(2) bond lengths. There are four shorter (3.17 Å) and two longer (3.21 Å) Y(1)-Ge(1) bond lengths. Fe(1) is bonded in a 5-coordinate geometry to five equivalent Y(1), one Ge(1), and four equivalent Ge(2) atoms. The Fe(1)-Ge(1) bond length is 2.29 Å. There are two shorter (2.36 Å) and two longer (2.38 Å) Fe(1)-Ge(2) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Y(1), one Fe(1), and two equivalent Ge(1) atoms. Both Ge(1)-Ge(1) bond lengths are 2.60 Å. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Y(1) and four equivalent Fe(1) atoms.
