EuAuIn2 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 13-coordinate geometry to three equivalent Au(1) and ten equivalent In(1) atoms. Au(1) is bonded in a 9-coordinate geometry to three equivalent Eu(1) and six equivalent In(1) atoms. In(1) is bonded in a 3-coordinate geometry to five equivalent Eu(1) and three equivalent Au(1) atoms.
EuAuIn2 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 13-coordinate geometry to three equivalent Au(1) and ten equivalent In(1) atoms. There is one shorter (3.19 Å) and two longer (3.33 Å) Eu(1)-Au(1) bond lengths. There are a spread of Eu(1)-In(1) bond distances ranging from 3.33-3.65 Å. Au(1) is bonded in a 9-coordinate geometry to three equivalent Eu(1) and six equivalent In(1) atoms. There are two shorter (2.86 Å) and four longer (2.90 Å) Au(1)-In(1) bond lengths. In(1) is bonded in a 3-coordinate geometry to five equivalent Eu(1) and three equivalent Au(1) atoms.
