Materials Data on Rb2P by Materials Project
Rb2P is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to four equivalent P2- atoms to form a mixture of edge and corner-sharing RbP4 tetrahedra. There are one shorter (3.40 Å) and three longer (3.47 Å) Rb–P bond lengths. In the second Rb1+ site, Rb1+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent P2- atoms. There are two shorter (3.62 Å) and one longer (3.64 Å) Rb–P bond lengths. P2- is bonded in a 7-coordinate geometry to seven Rb1+ atoms.
