Ni Sn Os Os
Os2NiSn crystallizes in the triclinic P1 space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 3-coordinate geometry to one Os(2), one Ni(1), and one Sn(1) atom. The Os(1)-Os(2) bond length is 1.36 Å. The Os(1)-Ni(1) bond length is 2.66 Å. The Os(1)-Sn(1) bond length is 2.15 Å. In the second Os site, Os(2) is bonded in a 5-coordinate geometry to one Os(1), two equivalent Ni(1), and two equivalent Sn(1) atoms. There is one shorter (2.11 Å) and one longer (2.39 Å) Os(2)-Ni(1) bond length. There is one shorter (2.19 Å) and one longer (2.46 Å) Os(2)-Sn(1) bond length. Ni(1) is bonded in a 4-coordinate geometry to one Os(1), two equivalent Os(2), and one Sn(1) atom. The Ni(1)-Sn(1) bond length is 1.82 Å. Sn(1) is bonded in a 3-coordinate geometry to one Os(1), two equivalent Os(2), and one Ni(1) atom.
