Sr Y Y Cu
SrY2Cu crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrY2Cu cluster. Sr(1) is bonded in a distorted single-bond geometry to one Y(1), one Y(2), and one Cu(1) atom. The Sr(1)-Y(1) bond length is 1.99 Å. The Sr(1)-Y(2) bond length is 1.99 Å. The Sr(1)-Cu(1) bond length is 1.64 Å. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 3-coordinate geometry to one Sr(1), one Y(2), and one Cu(1) atom. The Y(1)-Y(2) bond length is 1.22 Å. The Y(1)-Cu(1) bond length is 2.17 Å. In the second Y site, Y(2) is bonded in a 2-coordinate geometry to one Sr(1) and one Y(1) atom. Cu(1) is bonded in a distorted single-bond geometry to one Sr(1) and one Y(1) atom.
