Sr Cu Ni
SrNiCu is Cyanogen Chloride-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrNiCu cluster. Sr(1) is bonded in a linear geometry to one Ni(1) and one Cu(1) atom. The Sr(1)-Ni(1) bond length is 0.51 Å. The Sr(1)-Cu(1) bond length is 0.51 Å. Ni(1) is bonded in a single-bond geometry to one Sr(1) atom. Cu(1) is bonded in a single-bond geometry to one Sr(1) atom.
