Materials Data on Rb2P2Pt by Materials Project

Rb2PtP2 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 P3- atoms. There are two shorter (3.47 Å) and four longer (3.70 Å) Rb–P bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 2-coordinate geometry to six equivalent P3- atoms. There are two shorter (3.44 Å) and four longer (3.88 Å) Rb–P bond lengths. Pt4+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent P3- atoms. All Pt–P bond lengths are 2.42 Å. P3- is bonded in a 9-coordinate geometry to six Rb1+, two equivalent Pt4+, and one P3- atom. The P–P bond length is 2.19 Å.
