Materials Data on CdAs3 by Materials Project
CdAs3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Cd2+ is bonded to twelve equivalent As+0.67- atoms to form a mixture of face and corner-sharing CdAs12 cuboctahedra. There are six shorter (3.07 Å) and six longer (3.08 Å) Cd–As bond lengths. As+0.67- is bonded in a distorted see-saw-like geometry to four equivalent Cd2+ atoms.
