description: Rb2Zn3(P2O7)2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 3.01–3.38 Å. In the second Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.91–3.50 Å. There are three inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four PO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.96–1.99 Å. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four PO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.94–1.99 Å. In the third Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four PO4 tetrahedra. There is one shorter (1.96 Å) and three longer (1.97 Å) Zn–O bond length. There are four inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra and corners with three ZnO4 tetrahedra. There is three shorter (1.53 Å) and one longer (1.63 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra and corners with three ZnO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.53–1.62 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra and corners with three ZnO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.52–1.63 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra and corners with three ZnO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.52–1.63 Å. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Zn2+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one Zn2+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+ and two P5+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Zn2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Zn2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+, one Zn2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Rb1+, one Zn2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Zn2+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one Zn2+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Zn2+, and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+ and two P5+ atoms. In the twelfth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Zn2+, and one P5+ atom.
