The crystal structure described by GaBr2 is Indium-like structured and crystallizes in the trigonal R3c space group. The structure is zero-dimensional and consists of eighteen GaBr2 clusters. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted single-bond geometry to one Br(1) atom. In the second Ga site, Ga(2) is bonded in a tetrahedral geometry to one Br(1), one Br(2), one Br(3), and one Br(4) atom. There are four inequivalent Br sites. In the first Br site, Br(1) is bonded in an L-shaped geometry to one Ga(1) and one Ga(2) atom. In the second Br site, Br(2) is bonded in a single-bond geometry to one Ga(2) atom. In the third Br site, Br(3) is bonded in a single-bond geometry to one Ga(2) atom. In the fourth Br site, Br(4) is bonded in a single-bond geometry to one Ga(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
