The material structure described by Y15Ni32 is Bergman Structure: Mg32(Al,Zn)49 Bergman-derived structured and crystallizes in the cubic F-43m space group. There are four inequivalent Y sites. In the first Y site, Y(1) is bonded in a 12-coordinate geometry to twelve equivalent Ni(4) atoms. In the second Y site, Y(2) is bonded in a 6-coordinate geometry to three equivalent Ni(1), three equivalent Ni(4), and six equivalent Ni(3) atoms. In the third Y site, Y(3) is bonded in a 12-coordinate geometry to three equivalent Ni(2), three equivalent Ni(3), and six equivalent Ni(4) atoms. In the fourth Y site, Y(4) is bonded in a 12-coordinate geometry to two equivalent Ni(1), two equivalent Ni(2), four equivalent Ni(3), and four equivalent Ni(4) atoms. There are four inequivalent Ni sites. In the first Ni site, Ni(2) is bonded to three equivalent Y(3), three equivalent Y(4), three equivalent Ni(2), and three equivalent Ni(3) atoms to form a mixture of corner, edge, and face-sharing NiY6Ni6 cuboctahedra. In the second Ni site, Ni(3) is bonded in a 11-coordinate geometry to one Y(3), two equivalent Y(2), two equivalent Y(4), one Ni(2), two equivalent Ni(4), and three equivalent Ni(3) atoms. In the third Ni site, Ni(4) is bonded to one Y(1), one Y(2), two equivalent Y(3), two equivalent Y(4), one Ni(1), two equivalent Ni(3), and three equivalent Ni(4) atoms to form a mixture of corner, edge, and face-sharing NiY6Ni6 cuboctahedra. In the fourth Ni site, Ni(1) is bonded in a 12-coordinate geometry to three equivalent Y(2), three equivalent Y(4), three equivalent Ni(1), and three equivalent Ni(4) atoms. is represented by the CIF card [CIF]
