The structure described by Eu2AuGe3 crystallizes in the orthorhombic Fmmm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded to two equivalent Au(1), two equivalent Ge(1), and eight equivalent Ge(2) atoms to form EuGe10Au2 cuboctahedra that share edges with four equivalent Eu(1)Ge10Au2 cuboctahedra, edges with eight equivalent Eu(2)Ge8Au4 cuboctahedra, faces with four equivalent Eu(1)Ge10Au2 cuboctahedra, and faces with four equivalent Eu(2)Ge8Au4 cuboctahedra. In the second Eu site, Eu(2) is bonded to four equivalent Au(1), four equivalent Ge(1), and four equivalent Ge(2) atoms to form EuGe8Au4 cuboctahedra that share edges with four equivalent Eu(2)Ge8Au4 cuboctahedra, edges with eight equivalent Eu(1)Ge10Au2 cuboctahedra, faces with four equivalent Eu(1)Ge10Au2 cuboctahedra, and faces with four equivalent Eu(2)Ge8Au4 cuboctahedra. Au(1) is bonded in a distorted trigonal planar geometry to two equivalent Eu(1), four equivalent Eu(2), one Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted single-bond geometry to two equivalent Eu(1), four equivalent Eu(2), one Au(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a distorted single-bond geometry to two equivalent Eu(2), four equivalent Eu(1), one Au(1), one Ge(1), and one Ge(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
