The crystal structure described by EuNi5In crystallizes in the trigonal R-3m space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a distorted hexagonal planar geometry to six equivalent Ni(1), twelve equivalent Ni(2), and two equivalent In(1) atoms. In the second Eu site, Eu(2) is bonded in a 18-coordinate geometry to six equivalent Ni(2), six equivalent Ni(3), and six equivalent In(1) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 12-coordinate geometry to three equivalent Eu(1), three equivalent Ni(1), and six equivalent Ni(2) atoms. In the second Ni site, Ni(2) is bonded to one Eu(2), two equivalent Eu(1), one Ni(3), two equivalent Ni(1), four equivalent Ni(2), and two equivalent In(1) atoms to form a mixture of edge, face, and corner-sharing NiEu3In2Ni7 cuboctahedra. In the third Ni site, Ni(3) is bonded in a 10-coordinate geometry to three equivalent Eu(2), three equivalent Ni(2), and four equivalent In(1) atoms. In(1) is bonded in a 14-coordinate geometry to one Eu(1), three equivalent Eu(2), four equivalent Ni(3), and six equivalent Ni(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
