Materials Data on GaCuBr4 by Materials Project
CuGaBr4 crystallizes in the tetragonal P-42c space group. The structure is three-dimensional. Cu1+ is bonded to four equivalent Br1- atoms to form CuBr4 tetrahedra that share corners with four equivalent GaBr4 tetrahedra. All Cu–Br bond lengths are 2.47 Å. Ga3+ is bonded to four equivalent Br1- atoms to form GaBr4 tetrahedra that share corners with four equivalent CuBr4 tetrahedra. All Ga–Br bond lengths are 2.38 Å. Br1- is bonded in a water-like geometry to one Cu1+ and one Ga3+ atom.
