Eu2Ge is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. In the second Eu site, Eu(2) is bonded to four equivalent Ge(1) atoms to form a mixture of corner and edge-sharing EuGe4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Eu(2) and five equivalent Eu(1) atoms.
Eu2Ge is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. There are a spread of Eu(1)-Ge(1) bond distances ranging from 3.20-3.67 Å. In the second Eu site, Eu(2) is bonded to four equivalent Ge(1) atoms to form a mixture of corner and edge-sharing EuGe4 tetrahedra. There are a spread of Eu(2)-Ge(1) bond distances ranging from 3.07-3.14 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Eu(2) and five equivalent Eu(1) atoms.
