K K Ta Te
K2TaTe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2TaTe clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Ta(1) atom. The K(1)-Ta(1) bond length is 1.95 Å. In the second K site, K(2) is bonded in a single-bond geometry to one Te(1) atom. The K(2)-Te(1) bond length is 0.48 Å. Ta(1) is bonded in a bent 150 degrees geometry to one K(1) and one Te(1) atom. The Ta(1)-Te(1) bond length is 2.37 Å. Te(1) is bonded in a single-bond geometry to one K(2) and one Ta(1) atom.
