Ba2MgSi2 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Ba2MgSi2 cluster. Ba(1) is bonded in a single-bond geometry to one Si(1) atom. Mg(1) is bonded in a linear geometry to two equivalent Si(1) atoms. Si(1) is bonded in a linear geometry to one Ba(1) and one Mg(1) atom.
