The material described by Y3Ge4 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 7-coordinate geometry to three equivalent Ge(1) and four equivalent Ge(3) atoms. In the second Y site, Y(2) is bonded in a 8-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Y(1), four equivalent Y(2), and two equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 4-coordinate geometry to four equivalent Y(2) and four equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Y(1), four equivalent Y(2), one Ge(1), and two equivalent Ge(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
