Ga2AsCl crystallizes in the monoclinic Cm space group. Ga(1) is bonded in a 2-coordinate geometry to three equivalent As(1) and one Cl(1) atom. There are a spread of Ga(1)-As(1) bond distances ranging from 2.68-3.05 Å. The Ga(1)-Cl(1) bond length is 2.68 Å. As(1) is bonded in a 6-coordinate geometry to six equivalent Ga(1) atoms. Cl(1) is bonded in a 2-coordinate geometry to two equivalent Ga(1) atoms.
