Nb Ge Os Os
NbOs2Ge crystallizes in the triclinic P1 space group. Nb(1) is bonded in a 1-coordinate geometry to one Os(2), two equivalent Os(1), and one Ge(1) atom. The Nb(1)-Os(2) bond length is 1.60 Å. There is one shorter (2.23 Å) and one longer (2.35 Å) Nb(1)-Os(1) bond length. The Nb(1)-Ge(1) bond length is 2.65 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 3-coordinate geometry to two equivalent Nb(1) and one Ge(1) atom. The Os(1)-Ge(1) bond length is 2.45 Å. In the second Os site, Os(2) is bonded in a 3-coordinate geometry to one Nb(1) and two equivalent Ge(1) atoms. There is one shorter (1.44 Å) and one longer (2.10 Å) Os(2)-Ge(1) bond length. Ge(1) is bonded in a 4-coordinate geometry to one Nb(1), one Os(1), and two equivalent Os(2) atoms.
