The material described by Ni crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two Ni clusters. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a single-bond geometry to one Ni(2) atom. In the second Ni site, Ni(2) is bonded in a distorted single-bond geometry to one Ni(1) atom. is represented by the CIF file [CIF]
