Materials Data on Rb2NaMnF6 by Materials Project
Rb2NaMnF6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Rb1+ is bonded to twelve F1- atoms to form RbF12 cuboctahedra that share corners with twelve equivalent RbF12 cuboctahedra, faces with six equivalent RbF12 cuboctahedra, faces with four equivalent NaF6 octahedra, and faces with four equivalent MnF6 octahedra. There are four shorter (3.01 Å) and eight longer (3.08 Å) Rb–F bond lengths. Na1+ is bonded to six F1- atoms to form NaF6 octahedra that share corners with six equivalent MnF6 octahedra and faces with eight equivalent RbF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.30 Å) and four longer (2.35 Å) Na–F bond lengths. Mn3+ is bonded to six F1- atoms to form MnF6 octahedra that share corners with six equivalent NaF6 octahedra and faces with eight equivalent RbF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (1.91 Å) and two longer (2.14 Å) Mn–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted linear geometry to four equivalent Rb1+, one Na1+, and one Mn3+ atom. In the second F1- site, F1- is bonded in a distorted linear geometry to four equivalent Rb1+, one Na1+, and one Mn3+ atom.
