CsEuCl3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2) and six equivalent Cl(1) atoms. Eu(1) is bonded to two equivalent Cl(2) and four equivalent Cl(1) atoms to form corner-sharing EuCl6 octahedra. The corner-sharing octahedral tilt angles range from 20-23°. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 5-coordinate geometry to three equivalent Cs(1) and two equivalent Eu(1) atoms. In the second Cl site, Cl(2) is bonded in a distorted see-saw-like geometry to two equivalent Cs(1) and two equivalent Eu(1) atoms.
CsEuCl3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2) and six equivalent Cl(1) atoms. There is one shorter (3.54 Å) and one longer (3.59 Å) Cs(1)-Cl(2) bond length. There are a spread of Cs(1)-Cl(1) bond distances ranging from 3.54-3.86 Å. Eu(1) is bonded to two equivalent Cl(2) and four equivalent Cl(1) atoms to form corner-sharing EuCl6 octahedra. The corner-sharing octahedral tilt angles range from 20-23°. Both Eu(1)-Cl(2) bond lengths are 2.85 Å. All Eu(1)-Cl(1) bond lengths are 2.85 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 5-coordinate geometry to three equivalent Cs(1) and two equivalent Eu(1) atoms. In the second Cl site, Cl(2) is bonded in a distorted see-saw-like geometry to two equivalent Cs(1) and two equivalent Eu(1) atoms.
