EuCl2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 9-coordinate geometry to four equivalent Cl(2) and five equivalent Cl(1) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded to four equivalent Eu(1) atoms to form a mixture of corner and edge-sharing ClEu4 tetrahedra. In the second Cl site, Cl(1) is bonded in a 5-coordinate geometry to five equivalent Eu(1) atoms.
