Materials Data on Rb3P by Materials Project
Rb3P is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to four equivalent Rb1+ and four equivalent P3- atoms to form a mixture of distorted edge, corner, and face-sharing RbRb4P4 tetrahedra. All Rb–Rb bond lengths are 3.66 Å. All Rb–P bond lengths are 3.66 Å. In the second Rb1+ site, Rb1+ is bonded in a body-centered cubic geometry to eight equivalent Rb1+ atoms. P3- is bonded in a body-centered cubic geometry to eight equivalent Rb1+ atoms.
