The structure described by Rb2P is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded to four equivalent P(1) atoms to form a mixture of distorted corner and edge-sharing RbP4 tetrahedra. In the second Rb site, Rb(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent P(1) atoms. P(1) is bonded in a 7-coordinate geometry to three equivalent Rb(2) and four equivalent Rb(1) atoms. is represented by the CIF card [CIF]
