Materials Data on Rb2P3 by Materials Project
Rb2P3 crystallizes in the orthorhombic Fmmm space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight P+0.67- atoms. There are four shorter (3.62 Å) and four longer (3.68 Å) Rb–P bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 10-coordinate geometry to ten P+0.67- atoms. There are a spread of Rb–P bond distances ranging from 3.47–3.62 Å. There are two inequivalent P+0.67- sites. In the first P+0.67- site, P+0.67- is bonded in a 2-coordinate geometry to six Rb1+ and two equivalent P+0.67- atoms. Both P–P bond lengths are 2.17 Å. In the second P+0.67- site, P+0.67- is bonded in a 8-coordinate geometry to six Rb1+ and two P+0.67- atoms. The P–P bond length is 2.17 Å.
