Cr In Cu Cu
Cu2CrIn is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Cu2CrIn cluster. Cr(1) is bonded in a 2-coordinate geometry to one Cu(1) and one In(1) atom. The Cr(1)-Cu(1) bond length is 0.30 Å. The Cr(1)-In(1) bond length is 0.30 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a single-bond geometry to one Cr(1), one Cu(2), and one In(1) atom. The Cu(1)-Cu(2) bond length is 0.37 Å. The Cu(1)-In(1) bond length is 0.06 Å. In the second Cu site, Cu(2) is bonded in a 2-coordinate geometry to one Cu(1) and one In(1) atom. The Cu(2)-In(1) bond length is 0.37 Å. In(1) is bonded in a single-bond geometry to one Cr(1), one Cu(1), and one Cu(2) atom.
