The crystal structure described by Eu2Zn3Ge 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 Zn(2), eight equivalent Zn(1), and two equivalent Ge(1) atoms to form EuZn10Ge2 cuboctahedra that share edges with four equivalent Eu(1)Zn10Ge2 cuboctahedra, edges with eight equivalent Eu(2)Zn8Ge4 cuboctahedra, faces with four equivalent Eu(1)Zn10Ge2 cuboctahedra, and faces with four equivalent Eu(2)Zn8Ge4 cuboctahedra. In the second Eu site, Eu(2) is bonded to four equivalent Zn(1), four equivalent Zn(2), and four equivalent Ge(1) atoms to form EuZn8Ge4 cuboctahedra that share edges with four equivalent Eu(2)Zn8Ge4 cuboctahedra, edges with eight equivalent Eu(1)Zn10Ge2 cuboctahedra, faces with four equivalent Eu(1)Zn10Ge2 cuboctahedra, and faces with four equivalent Eu(2)Zn8Ge4 cuboctahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted single-bond geometry to two equivalent Eu(2), four equivalent Eu(1), one Zn(1), one Zn(2), and one Ge(1) atom. In the second Zn site, Zn(2) is bonded in a 9-coordinate geometry to two equivalent Eu(1), four equivalent Eu(2), two equivalent Zn(1), and one Ge(1) atom. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Eu(1), four equivalent Eu(2), one Zn(2), and two equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
