YOs2Cu crystallizes in the triclinic P1 space group. Y(1) is bonded in a 11-coordinate geometry to six equivalent Y(1), two equivalent Os(1), two equivalent Os(2), and one Cu(1) atom. There are four shorter (2.81 Å) and two longer (3.22 Å) Y(1)-Y(1) bond lengths. There is one shorter (3.33 Å) and one longer (3.59 Å) Y(1)-Os(1) bond length. There is one shorter (3.33 Å) and one longer (3.59 Å) Y(1)-Os(2) bond length. The Y(1)-Cu(1) bond length is 3.18 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted linear geometry to two equivalent Y(1), one Os(2), and two equivalent Cu(1) atoms. The Os(1)-Os(2) bond length is 2.43 Å. There is one shorter (1.09 Å) and one longer (1.72 Å) Os(1)-Cu(1) bond length. In the second Os site, Os(2) is bonded in a 11-coordinate geometry to two equivalent Y(1), one Os(1), six equivalent Os(2), and two equivalent Cu(1) atoms. There are four shorter (2.81 Å) and two longer (3.22 Å) Os(2)-Os(2) bond lengths. There is one shorter (2.64 Å) and one longer (2.95 Å) Os(2)-Cu(1) bond length. Cu(1) is bonded in a distorted linear geometry to one Y(1), two equivalent Os(1), and two equivalent Os(2) atoms.
