MgSi is Tetraauricupride structured and crystallizes in the tetragonal P4/mmm space group. Mg(1) is bonded to four equivalent Mg(1) and eight equivalent Si(1) atoms to form a mixture of distorted edge, corner, and face-sharing MgMg4Si8 cuboctahedra. Si(1) is bonded in a 8-coordinate geometry to eight equivalent Mg(1) atoms.
