Zn Ga Br
ZnGaBr is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ZnGaBr cluster. Zn(1) is bonded in a single-bond geometry to one Br(1) atom. The Zn(1)-Br(1) bond length is 1.21 Å. Ga(1) is bonded in a distorted single-bond geometry to one Br(1) atom. The Ga(1)-Br(1) bond length is 1.42 Å. Br(1) is bonded in a water-like geometry to one Zn(1) and one Ga(1) atom.
