The material structure described by MgYbSi crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded to four equivalent Si(1) atoms to form a mixture of distorted corner and edge-sharing MgSi4 tetrahedra. Yb(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 Yb(1) atoms. is represented by the CIF card [CIF]
