Materials Data on SrLaMnWO6 by Materials Project
SrLaMnWO6 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. Sr2+ is bonded in a 12-coordinate geometry to eight O2- atoms. There are four shorter (2.63 Å) and four longer (2.90 Å) Sr–O bond lengths. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.45 Å) and four longer (2.90 Å) La–O bond lengths. W5+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 0–30°. There is two shorter (1.94 Å) and four longer (2.05 Å) W–O bond length. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 0–30°. There are two shorter (2.11 Å) and four longer (2.19 Å) Mn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to two equivalent Sr2+, two equivalent La3+, one W5+, and one Mn2+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one Sr2+, one La3+, one W5+, and one Mn2+ atom.
