EuIrSn2 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 13-coordinate geometry to three equivalent Ir(1) and ten equivalent Sn(1) atoms. Ir(1) is bonded in a 9-coordinate geometry to three equivalent Eu(1) and six equivalent Sn(1) atoms. Sn(1) is bonded in a 5-coordinate geometry to five equivalent Eu(1) and three equivalent Ir(1) atoms.
EuIrSn2 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 13-coordinate geometry to three equivalent Ir(1) and ten equivalent Sn(1) atoms. There is one shorter (3.11 Å) and two longer (3.34 Å) Eu(1)-Ir(1) bond lengths. There are a spread of Eu(1)-Sn(1) bond distances ranging from 3.29-3.60 Å. Ir(1) is bonded in a 9-coordinate geometry to three equivalent Eu(1) and six equivalent Sn(1) atoms. There are two shorter (2.74 Å) and four longer (2.76 Å) Ir(1)-Sn(1) bond lengths. Sn(1) is bonded in a 5-coordinate geometry to five equivalent Eu(1) and three equivalent Ir(1) atoms.
