The structure described by CdAs3 crystallizes in the hexagonal P6_3/mmc space group. Cd(1) is bonded to twelve equivalent As(1) atoms to form a mixture of corner and face-sharing CdAs12 cuboctahedra. As(1) is bonded in a distorted see-saw-like geometry to four equivalent Cd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
