Materials Data on AsH2C2NCl2O by Materials Project
(C2NH2)2(AsOCl)2Cl2 crystallizes in the orthorhombic Cmce space group. The structure is one-dimensional and consists of eight ch3nc molecules; eight hydrochloric acid molecules; and four AsOCl ribbons oriented in the (1, 0, 0) direction. In each AsOCl ribbon, As3- is bonded in a 2-coordinate geometry to two equivalent O2- and one Cl1- atom. Both As–O bond lengths are 1.84 Å. The As–Cl bond length is 2.32 Å. O2- is bonded in a bent 120 degrees geometry to two equivalent As3- atoms. Cl1- is bonded in a single-bond geometry to one As3- atom.
