Ga Te Se Se
GaTeSe2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one GaTeSe2 cluster. Ga(1) is bonded in a 2-coordinate geometry to one Se(1) and one Se(2) atom. The Ga(1)-Se(1) bond length is 0.72 Å. The Ga(1)-Se(2) bond length is 0.91 Å. Te(1) is bonded in an L-shaped geometry to one Se(1) and one Se(2) atom. The Te(1)-Se(1) bond length is 0.52 Å. The Te(1)-Se(2) bond length is 0.57 Å. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a 3-coordinate geometry to one Ga(1), one Te(1), and one Se(2) atom. The Se(1)-Se(2) bond length is 0.74 Å. In the second Se site, Se(2) is bonded in a 3-coordinate geometry to one Ga(1), one Te(1), and one Se(1) atom.
