Materials Data on GaBr3 by Materials Project
GaBr3 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two GaBr3 clusters. Ga3+ is bonded to four Br1- atoms to form edge-sharing GaBr4 tetrahedra. There are two shorter (2.29 Å) and two longer (2.50 Å) Ga–Br bond lengths. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Ga3+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one Ga3+ atom. In the third Br1- site, Br1- is bonded in an L-shaped geometry to two equivalent Ga3+ atoms.
