Materials Data on CuH12N2(Cl2O)2 by Materials Project

Abstract

CuH4(OCl2)2(NH4)2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional and consists of four ammonium molecules and one CuH4(OCl2)2 framework. In the CuH4(OCl2)2 framework, Cu2+ is bonded in a distorted square co-planar geometry to two equivalent O2- and four Cl1- atoms. Both Cu–O bond lengths are 1.99 Å. There are two shorter (2.28 Å) and two longer (3.06 Å) Cu–Cl bond lengths. H1+ is bonded in a single-bond geometry to one O2- and one Cl1- atom. The H–O bond length is 1.00 Å. The H–Cl bond length is 2.08 Å. O2- is bonded in a distorted trigonal planar geometry to one Cu2+ and two equivalent H1+ atoms. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 3-coordinate geometry to one Cu2+ and two equivalent H1+ atoms. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Cu2+ atom.
