The structure described by Er3NiGe2 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Er sites. In the first Er site, Er(1) is bonded in a 6-coordinate geometry to one Ni(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the second Er site, Er(2) is bonded in a 7-coordinate geometry to two equivalent Ni(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. In the third Er site, Er(3) is bonded in a 8-coordinate geometry to three equivalent Ni(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to one Er(1), two equivalent Er(2), three equivalent Er(3), one Ge(2), and two equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Er(1), two equivalent Er(2), three equivalent Er(3), and two equivalent Ni(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Er(3), three equivalent Er(1), three equivalent Er(2), and one Ni(1) atom. is represented by the CIF file [CIF]
