RuAsBr2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RuAsBr2 clusters. Ru(1) is bonded in a 2-coordinate geometry to two equivalent Br(1) atoms. Both Ru(1)-Br(1) bond lengths are 2.25 Å. As(1) is bonded in a 2-coordinate geometry to two equivalent Br(1) atoms. Both As(1)-Br(1) bond lengths are 2.25 Å. Br(1) is bonded in a 2-coordinate geometry to one Ru(1) and one As(1) atom.
