Materials Data on Rb2As2Pt by Materials Project

Rb2PtAs2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 2-coordinate geometry to six equivalent As3- atoms. There are two shorter (3.55 Å) and four longer (3.75 Å) Rb–As bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six equivalent As3- atoms. There are two shorter (3.51 Å) and four longer (3.89 Å) Rb–As bond lengths. Pt4+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent As3- atoms. All Pt–As bond lengths are 2.54 Å. As3- is bonded in a 9-coordinate geometry to six Rb1+, two equivalent Pt4+, and one As3- atom. The As–As bond length is 2.46 Å.
