The material structure described by Eu2NiGe3 crystallizes in the trigonal P3m1 space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 9-coordinate geometry to three equivalent Ni(1), three equivalent Ge(2), and three equivalent Ge(3) atoms. In the second Eu site, Eu(2) is bonded in a 9-coordinate geometry to three equivalent Ni(1), three equivalent Ge(1), and three equivalent Ge(2) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Eu(1), three equivalent Eu(2), and three equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to three equivalent Eu(2) and three equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Eu(1), three equivalent Eu(2), and three equivalent Ni(1) atoms. In the third Ge site, Ge(3) is bonded to three equivalent Eu(1) and three equivalent Ge(1) atoms to form distorted edge-sharing GeEu3Ge3 octahedra. is represented by the CIF card [CIF]
