Cr Cr Cu Pt
(Cr)2PtCu is Cubic alpha N2-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Cr cluster and one PtCu cluster. In the Cr cluster, there are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a single-bond geometry to one Cr(2) atom. The Cr(1)-Cr(2) bond length is 0.43 Å. In the second Cr site, Cr(2) is bonded in a single-bond geometry to one Cr(1) atom. In the PtCu cluster, Pt(1) is bonded in a single-bond geometry to one Cu(1) atom. The Pt(1)-Cu(1) bond length is 0.45 Å. Cu(1) is bonded in a single-bond geometry to one Pt(1) atom.
