Materials Data on AsCl3 by Materials Project
AsCl3 is Ammonia-like structured and crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of four trichloroarsine molecules. As3+ is bonded in a distorted trigonal non-coplanar geometry to three Cl1- atoms. All As–Cl bond lengths are 2.21 Å. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one As3+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one As3+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one As3+ atom.
