Materials Data on Sr3Mn2O7 by Materials Project

Kristin Persson
Sr3Mn2O7 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with four equivalent SrO12 cuboctahedra, faces with four equivalent SrO12 cuboctahedra, and faces with eight equivalent MnO6 octahedra. There are four shorter (2.74 Å) and eight longer (2.75 Å) Sr–O bond lengths. In the second Sr2+ site, Sr2+...
