BaMgSn is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ba(1) is bonded to four equivalent Ba(1), four equivalent Mg(1), and four equivalent Sn(1) atoms to form a mixture of distorted face and corner-sharing BaBa4Mg4Sn4 cuboctahedra. Mg(1) is bonded in a single-bond geometry to four equivalent Ba(1) and one Sn(1) atom. Sn(1) is bonded in a 5-coordinate geometry to four equivalent Ba(1) and one Mg(1) atom.
