Materials Data on Cs2As2Pd by Materials Project

Cs2PdAs2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to six equivalent As3- atoms. There are two shorter (3.78 Å) and four longer (3.83 Å) Cs–As bond lengths. In the second Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to six equivalent As3- atoms. There are two shorter (3.69 Å) and four longer (4.03 Å) Cs–As bond lengths. Pd4+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent As3- atoms. All Pd–As bond lengths are 2.54 Å. As3- is bonded in a 9-coordinate geometry to six Cs1+, two equivalent Pd4+, and one As3- atom. The As–As bond length is 2.43 Å.
