Na Na Re Ni
Na2ReNi crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Na2ReNi cluster. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 2-coordinate geometry to one Na(2) and one Ni(1) atom. The Na(1)-Na(2) bond length is 0.47 Å. The Na(1)-Ni(1) bond length is 2.22 Å. In the second Na site, Na(2) is bonded in a 2-coordinate geometry to one Na(1) and one Re(1) atom. The Na(2)-Re(1) bond length is 2.22 Å. Re(1) is bonded in a distorted single-bond geometry to one Na(2) atom. Ni(1) is bonded in a distorted single-bond geometry to one Na(1) atom.
