GaHCl2 is Protactinium structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four dichlorogallane molecules. Ga(1) is bonded to one H(1), one Cl(1), and two equivalent Cl(2) atoms to form distorted edge-sharing GaHCl3 tetrahedra. H(1) is bonded in a single-bond geometry to one Ga(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(2) is bonded in an L-shaped geometry to two equivalent Ga(1) atoms. In the second Cl site, Cl(1) is bonded in a single-bond geometry to one Ga(1) atom.

Ga(1) is bonded to one H(1), one Cl(1), and two equivalent Cl(2) atoms to form distorted edge-sharing GaHCl3 tetrahedra. The Ga(1)-H(1) bond length is 1.52 Å. The Ga(1)-Cl(1) bond length is 2.16 Å. There is one shorter (2.33 Å) and one longer (2.34 Å) Ga(1)-Cl(2) bond length. H(1) is bonded in a single-bond geometry to one Ga(1) atom. There are two inequivalent Cl sites.
