Ni Sn Sn Os
OsNiSn2 crystallizes in the triclinic P1 space group. Os(1) is bonded in a single-bond geometry to one Ni(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. The Os(1)-Ni(1) bond length is 0.39 Å. There is one shorter (2.69 Å) and one longer (3.06 Å) Os(1)-Sn(1) bond length. There is one shorter (2.90 Å) and one longer (3.25 Å) Os(1)-Sn(2) bond length. Ni(1) is bonded in a single-bond geometry to one Os(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. There is one shorter (2.90 Å) and one longer (3.25 Å) Ni(1)-Sn(1) bond length. There is one shorter (2.69 Å) and one longer (3.06 Å) Ni(1)-Sn(2) bond length. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to two equivalent Os(1), two equivalent Ni(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. Both Sn(1)-Sn(1) bond lengths are 3.21 Å. There is one shorter (1.98 Å) and one longer (2.63 Å) Sn(1)-Sn(2) bond length. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to two equivalent Os(1), two equivalent Ni(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. Both Sn(2)-Sn(2) bond lengths are 3.21 Å.
