EuMgSi crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded to four equivalent Si(1) atoms to form a mixture of distorted edge and corner-sharing MgSi4 tetrahedra. Eu(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to four equivalent Mg(1) and five equivalent Eu(1) atoms.
