CAs2H2Cl4 is Indium-like structured and crystallizes in the monoclinic Cc space group. The structure is zero-dimensional and consists of twelve methylenebis(dichloroarsine) molecules. C(1) is bonded in a distorted tetrahedral geometry to one As(1), one As(2), one H(1), and one H(2) atom. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted T-shaped geometry to one C(1), one Cl(1), and one Cl(2) atom. In the second As site, As(2) is bonded in a distorted T-shaped geometry to one C(1), one Cl(3), and one Cl(4) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1) atom. There are four inequivalent Cl sites. In the first Cl site, Cl(3) is bonded in a single-bond geometry to one As(2) atom. In the second Cl site, Cl(4) is bonded in a single-bond geometry to one As(2) atom. In the third Cl site, Cl(1) is bonded in a single-bond geometry to one As(1) atom. In the fourth Cl site, Cl(2) is bonded in a single-bond geometry to one As(1) atom.
