Zn Ga Ga S S S S
ZnGa2S4 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ZnGa2S4 clusters. Zn(1) is bonded in a linear geometry to one Ga(1) and one S(3) atom. The Zn(1)-Ga(1) bond length is 1.29 Å. The Zn(1)-S(3) bond length is 1.52 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a linear geometry to one Zn(1) and one S(2) atom. The Ga(1)-S(2) bond length is 1.57 Å. In the second Ga site, Ga(2) is bonded in a distorted linear geometry to one S(1) and one S(4) atom. The Ga(2)-S(1) bond length is 1.57 Å. The Ga(2)-S(4) bond length is 2.80 Å. There are four inequivalent S sites. In the first S site, S(1) is bonded in a single-bond geometry to one Ga(2) atom. In the second S site, S(2) is bonded in a single-bond geometry to one Ga(1) atom. In the third S site, S(3) is bonded in a linear geometry to one Zn(1) and one S(4) atom. The S(3)-S(4) bond length is 0.40 Å. In the fourth S site, S(4) is bonded in a linear geometry to one Ga(2) and one S(3) atom.
