The compound described by Eu3Ge5 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 10-coordinate geometry to two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. In the second Eu site, Eu(2) is bonded in a 9-coordinate geometry to one Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Eu(2), four equivalent Eu(1), one Ge(3), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Eu(2), four equivalent Eu(1), one Ge(3), and two equivalent Ge(1) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to one Eu(2), four equivalent Eu(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
