Co Cu Cu Ni
CoCuNiCu is alpha oxygen-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one 12357-13-0 molecule and one CoCu cluster. In the CoCu cluster, Co(1) is bonded in a single-bond geometry to one Cu(2) atom. The Co(1)-Cu(2) bond length is 0.56 Å. Cu(2) is bonded in a single-bond geometry to one Co(1) atom.
