Y Zn Os Os
YOs2Zn crystallizes in the triclinic P1 space group. Y(1) is bonded in a 2-coordinate geometry to one Os(1) and two equivalent Os(2) atoms. The Y(1)-Os(1) bond length is 3.18 Å. There is one shorter (3.18 Å) and one longer (3.44 Å) Y(1)-Os(2) bond length. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to one Y(1) and two equivalent Zn(1) atoms. There is one shorter (1.24 Å) and one longer (1.82 Å) Os(1)-Zn(1) bond length. In the second Os site, Os(2) is bonded in a 8-coordinate geometry to two equivalent Y(1), four equivalent Os(2), and two equivalent Zn(1) atoms. All Os(2)-Os(2) bond lengths are 2.86 Å. There is one shorter (2.58 Å) and one longer (2.91 Å) Os(2)-Zn(1) bond length. Zn(1) is bonded in a 2-coordinate geometry to two equivalent Os(1) and two equivalent Os(2) atoms.
