Materials Data on Cu3Se2(ClO3)2 by Materials Project

Abstract

Cu3(SeO3)2Cl2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one Cu3(SeO3)2Cl2 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to four O2- and one Cl1- atom to form distorted edge-sharing CuClO4 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.95–2.30 Å. The Cu–Cl bond length is 2.22 Å. In the second Cu2+ site, Cu2+ is bonded in a distorted square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.94 Å. Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.69 Å) and two longer (1.80 Å) Se–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cu2+ and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one Se4+ atom. Cl1- is bonded in a single-bond geometry to one Cu2+ atom.
