EuAl2Ge crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 14-coordinate geometry to four equivalent Al(1), five equivalent Al(2), and five equivalent Ge(1) atoms. There are two inequivalent Al sites. In the first Al site, Al(2) is bonded in a 2-coordinate geometry to five equivalent Eu(1), three equivalent Al(1), and two equivalent Ge(1) atoms. In the second Al site, Al(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), three equivalent Al(2), and two equivalent Ge(1) atoms. Ge(1) is bonded in a 7-coordinate geometry to five equivalent Eu(1), two equivalent Al(1), and two equivalent Al(2) atoms.
EuAl2Ge crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 14-coordinate geometry to four equivalent Al(1), five equivalent Al(2), and five equivalent Ge(1) atoms. There are two shorter (3.19 Å) and two longer (3.37 Å) Eu(1)-Al(1) bond lengths. There are a spread of Eu(1)-Al(2) bond distances ranging from 3.33-3.75 Å. There are a spread of Eu(1)-Ge(1) bond distances ranging from 3.14-3.51 Å. There are two inequivalent Al sites. In the first Al site, Al(2) is bonded in a 2-coordinate geometry to five equivalent Eu(1), three equivalent Al(1), and two equivalent Ge(1) atoms.
