Ta Ta Re Ge
Ta2ReGe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ta2ReGe cluster. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a single-bond geometry to one Ge(1) atom. The Ta(1)-Ge(1) bond length is 0.89 Å. In the second Ta site, Ta(2) is bonded in a distorted single-bond geometry to one Re(1) atom. The Ta(2)-Re(1) bond length is 2.02 Å. Re(1) is bonded in a 2-coordinate geometry to one Ta(2) and one Ge(1) atom. The Re(1)-Ge(1) bond length is 1.35 Å. Ge(1) is bonded in a 1-coordinate geometry to one Ta(1) and one Re(1) atom.
