Sr Ni Os Os
SrOs2Ni crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 7-coordinate geometry to one Os(1), three equivalent Os(2), and three equivalent Ni(1) atoms. The Sr(1)-Os(1) bond length is 2.74 Å. There are a spread of Sr(1)-Os(2) bond distances ranging from 2.55-3.87 Å. There are a spread of Sr(1)-Ni(1) bond distances ranging from 2.66-3.70 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted single-bond geometry to one Sr(1), one Os(2), and one Ni(1) atom. The Os(1)-Os(2) bond length is 1.52 Å. The Os(1)-Ni(1) bond length is 0.96 Å. In the second Os site, Os(2) is bonded in a 2-coordinate geometry to three equivalent Sr(1) and one Os(1) atom. Ni(1) is bonded in a distorted single-bond geometry to three equivalent Sr(1) and one Os(1) atom.
