Materials Data on Cu(HCl)2 by Materials Project
Cu(HCl)2 crystallizes in the orthorhombic Pmna space group. The structure is two-dimensional and consists of one Cu(HCl)2 sheet oriented in the (1, 0, 0) direction. Cu2+ is bonded in a square co-planar geometry to two equivalent H and two equivalent Cl1- atoms. Both Cu–H bond lengths are 1.59 Å. Both Cu–Cl bond lengths are 2.08 Å. H is bonded in a 3-coordinate geometry to one Cu2+ and two equivalent Cl1- atoms. Both H–Cl bond lengths are 2.36 Å. Cl1- is bonded in a distorted trigonal non-coplanar geometry to one Cu2+ and two equivalent H atoms.
