Materials Data on Sr2MnSbO6 by Materials Project

Abstract

Sr2MnSbO6 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. Sr2+ is bonded in a 12-coordinate geometry to eight O2- atoms. There are four shorter (2.64 Å) and four longer (2.77 Å) Sr–O bond lengths. Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent SbO6 octahedra. The corner-sharing octahedra tilt angles range from 0–22°. There are four shorter (1.96 Å) and two longer (2.27 Å) Mn–O bond lengths. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with six equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 0–22°. There are two shorter (1.98 Å) and four longer (2.02 Å) Sb–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Sr2+, one Mn3+, and one Sb5+ atom to form a mixture of distorted corner and edge-sharing OSr4MnSb octahedra. The corner-sharing octahedra tilt angles range from 0–6°. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+, one Mn3+, and one Sb5+ atom.
