Ta Ta Te Os
TaOsTaTe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one tellanylidenetantalum molecule and one TaOs cluster. In the TaOs cluster, Ta(2) is bonded in a distorted single-bond geometry to one Os(1) atom. The Ta(2)-Os(1) bond length is 1.60 Å. Os(1) is bonded in a distorted single-bond geometry to one Ta(2) atom.
