Ta Ta Al Cl
TaAlTaCl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TaAl cluster and one TaCl cluster. In the TaAl cluster, Ta(2) is bonded in a distorted single-bond geometry to one Al(1) atom. The Ta(2)-Al(1) bond length is 2.15 Å. Al(1) is bonded in a distorted single-bond geometry to one Ta(2) atom. In the TaCl cluster, Ta(1) is bonded in a distorted single-bond geometry to one Cl(1) atom. The Ta(1)-Cl(1) bond length is 3.07 Å. Cl(1) is bonded in a single-bond geometry to one Ta(1) atom.
