The compound described by Y(Ni2B)6 crystallizes in the trigonal R-3m space group. Y(1) is bonded in a 24-coordinate geometry to six equivalent Ni(2), twelve equivalent Ni(1), and six equivalent B(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(2) is bonded in a distorted T-shaped geometry to one Y(1) and three equivalent B(1) atoms. In the second Ni site, Ni(1) is bonded in a 4-coordinate geometry to two equivalent Y(1) and four equivalent B(1) atoms. B(1) is bonded in a 7-coordinate geometry to one Y(1), three equivalent Ni(2), and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
