Ta Ta Co Ag
CoTaTaAg crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CoTa cluster and one TaAg cluster. In the CoTa cluster, Ta(2) is bonded in a single-bond geometry to one Co(1) atom. The Ta(2)-Co(1) bond length is 0.84 Å. Co(1) is bonded in a single-bond geometry to one Ta(2) atom. In the TaAg cluster, Ta(1) is bonded in a single-bond geometry to one Ag(1) atom. The Ta(1)-Ag(1) bond length is 1.16 Å. Ag(1) is bonded in a single-bond geometry to one Ta(1) atom.
