Abstract

Rb2MgF4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Rb1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Rb–F bond distances ranging from 2.90–2.93 Å. Mg2+ is bonded to six F1- atoms to form corner-sharing MgF6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.03 Å) and four longer (2.06 Å) Mg–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded to five equivalent Rb1+ and one Mg2+ atom to form a mixture of distorted edge and corner-sharing FRb5Mg octahedra. The corner-sharing octahedra tilt angles range from 0–2°. In the second F1- site, F1- is bonded in a distorted linear geometry to four equivalent Rb1+ and two equivalent Mg2+ atoms.
