Materials Data on RbTiPO5 by Materials Project
RbTiOPO4 crystallizes in the orthorhombic Pna2_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 2.79–3.19 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 2.80–3.48 Å. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 41–43°. There are a spread of Ti–O bond distances ranging from 1.81–2.11 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 41–43°. There are a spread of Ti–O bond distances ranging from 1.77–2.16 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four TiO6 octahedra. The corner-sharing octahedra tilt angles range from 44–47°. There are a spread of P–O bond distances ranging from 1.55–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four TiO6 octahedra. The corner-sharing octahedra tilt angles range from 45–48°. There is one shorter (1.54 Å) and three longer (1.56 Å) P–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ti4+, and one P5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+, one Ti4+, and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ti4+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+ and two Ti4+ atoms. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+ and two Ti4+ atoms. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+, one Ti4+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one Ti4+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one Ti4+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to two Rb1+, one Ti4+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one Ti4+, and one P5+ atom.
