Materials Data on CdSnAs2 by Materials Project
CdSnAs2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Cd2+ is bonded to four equivalent As3- atoms to form CdAs4 tetrahedra that share corners with four equivalent CdAs4 tetrahedra and corners with eight equivalent SnAs4 tetrahedra. All Cd–As bond lengths are 2.69 Å. Sn4+ is bonded to four equivalent As3- atoms to form SnAs4 tetrahedra that share corners with four equivalent SnAs4 tetrahedra and corners with eight equivalent CdAs4 tetrahedra. All Sn–As bond lengths are 2.66 Å. As3- is bonded to two equivalent Cd2+ and two equivalent Sn4+ atoms to form corner-sharing AsCd2Sn2 tetrahedra.
