The material structure described by EuNi2GeSi crystallizes in the tetragonal I4mm space group. Eu(1) is bonded in a 16-coordinate geometry to eight equivalent Ni(1), four equivalent Ge(1), and four equivalent Si(1) atoms. Ni(1) is bonded in a 4-coordinate geometry to four equivalent Eu(1), two equivalent Ge(1), and two equivalent Si(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), four equivalent Ni(1), and one Si(1) atom. Si(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), four equivalent Ni(1), and one Ge(1) atom. is represented by the CIF file [CIF]
