Zr Zr Nb Os
Zr2NbOs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Zr2NbOs clusters. Zr(1) is bonded in a 2-coordinate geometry to one Nb(1) and one Os(1) atom. The Zr(1)-Nb(1) bond length is 2.06 Å. The Zr(1)-Os(1) bond length is 2.06 Å. Nb(1) is bonded in a 2-coordinate geometry to two equivalent Zr(1) atoms. Os(1) is bonded in a 2-coordinate geometry to two equivalent Zr(1) atoms.
