CdIn3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Cd(1) is bonded to twelve equivalent In(1) atoms to form CdIn12 cuboctahedra that share corners with six equivalent Cd(1)In12 cuboctahedra, corners with twelve equivalent In(1)Cd4In8 cuboctahedra, edges with eighteen equivalent In(1)Cd4In8 cuboctahedra, faces with eight equivalent Cd(1)In12 cuboctahedra, and faces with twelve equivalent In(1)Cd4In8 cuboctahedra. In(1) is bonded to four equivalent Cd(1) and eight equivalent In(1) atoms to form InCd4In8 cuboctahedra that share corners with four equivalent Cd(1)In12 cuboctahedra, corners with fourteen equivalent In(1)Cd4In8 cuboctahedra, edges with six equivalent Cd(1)In12 cuboctahedra, edges with twelve equivalent In(1)Cd4In8 cuboctahedra, faces with four equivalent Cd(1)In12 cuboctahedra, and faces with sixteen equivalent In(1)Cd4In8 cuboctahedra.

There are six shorter (3.27 Å) and six longer (3.35 Å) Cd(1)-In(1) bond lengths. In(1) is bonded to four equivalent Cd(1) and eight equivalent In(1) atoms to form InCd4In8 cuboctahedra that share corners with four equivalent Cd(1)In12 cuboctahedra, corners with fourteen equivalent In(1)Cd4In8 cuboctahedra, edges with six equivalent Cd(1)In12 cuboctahedra, edges with twelve equivalent In(1)Cd4In8 cuboctahedra, faces with four equivalent Cd(1)In12 cuboctahedra, and faces with sixteen equivalent In(1)Cd4In8 cuboctahedra. There are a spread of In(1)-In(1) bond distances ranging from 3.26-3.36 Å.
