Materials Data on Ba(MnSn)2 by Materials Project
Ba(MnSn)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba is bonded in a 8-coordinate geometry to eight equivalent Mn and eight equivalent Sn atoms. All Ba–Mn bond lengths are 3.82 Å. All Ba–Sn bond lengths are 3.70 Å. Mn is bonded to four equivalent Ba and four equivalent Sn atoms to form a mixture of distorted edge, corner, and face-sharing MnBa4Sn4 tetrahedra. All Mn–Sn bond lengths are 2.75 Å. Sn is bonded in a 9-coordinate geometry to four equivalent Ba, four equivalent Mn, and one Sn atom. The Sn–Sn bond length is 3.18 Å.
