Materials Data on RbScAsO4F by Materials Project
Abstract
RbScAsO4F 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 seven O2- and two F1- atoms. There are a spread of Rb–O bond distances ranging from 2.89–3.33 Å. There are one shorter (2.95 Å) and one longer (3.35 Å) Rb–F bond lengths. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to six O2- and two F1- atoms. There are a spread of Rb–O bond distances ranging from 2.89–3.31 Å. There are one shorter (2.93 Å) and one longer (3.24 Å) Rb–F bond lengths. There are two inequivalent Sc3+ sites. In the first Sc3+ site, Sc3+ is bonded to four O2- and two F1- atoms to form ScO4F2 octahedra that share corners with two equivalent ScO4F2 octahedra and corners with four AsO4 tetrahedra. The corner-sharing octahedral tilt angles are 48°. There are a spread of Sc–O bond distances ranging from 2.03–2.14 Å. There are one shorter (2.12 Å) and one longer (2.15 Å) Sc–F bond lengths. In the second Sc3+ site, Sc3+ is bonded to four O2- and two F1- atoms to form ScO4F2 octahedra thatmore »
