The material described by YMn2GeSi crystallizes in the tetragonal I4mm space group. Y(1) is bonded in a 8-coordinate geometry to four equivalent Ge(1) and four equivalent Si(1) atoms. Mn(1) is bonded to two equivalent Ge(1) and two equivalent Si(1) atoms to form a mixture of corner and edge-sharing MnSi2Ge2 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Y(1), four equivalent Mn(1), and one Si(1) atom. Si(1) is bonded in a 9-coordinate geometry to four equivalent Y(1), four equivalent Mn(1), and one Ge(1) atom. is represented by the CIF card [CIF]
