Materials Data on SrMnSn by Materials Project
SrMnSn is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sr is bonded in a 9-coordinate geometry to four equivalent Mn and five equivalent Sn atoms. All Sr–Mn bond lengths are 3.41 Å. There are four shorter (3.49 Å) and one longer (3.67 Å) Sr–Sn bond lengths. Mn is bonded in a 4-coordinate geometry to four equivalent Sr and four equivalent Sn atoms. All Mn–Sn bond lengths are 2.82 Å. Sn is bonded in a 9-coordinate geometry to five equivalent Sr and four equivalent Mn atoms.
