The structure described by Y4Ni is Iron carbide-like structured and crystallizes in the cubic Fd-3m space group. The structure is zero-dimensional and consists of eight Y4Ni clusters. Y(1) is bonded in a single-bond geometry to one Ni(1) atom. Ni(1) is bonded in a tetrahedral geometry to four equivalent Y(1) atoms. is represented by the CIF card [CIF]
