Tc As Os Os
TcOs2As crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TcOs2As cluster. Tc(1) is bonded in a linear geometry to one Os(2) and one As(1) atom. The Tc(1)-Os(2) bond length is 1.00 Å. The Tc(1)-As(1) bond length is 1.37 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to one Os(2) atom. The Os(1)-Os(2) bond length is 0.29 Å. In the second Os site, Os(2) is bonded in a linear geometry to one Tc(1) and one Os(1) atom. As(1) is bonded in a single-bond geometry to one Tc(1) atom.
