Materials Data on Cr(ClO2)3 by Materials Project

Abstract

(CrO6)2(Cl2)3 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four chlorine molecules, four hydrochloric acid molecules, and four CrO6 clusters. In each CrO6 cluster, Cr is bonded in a distorted rectangular see-saw-like geometry to four O atoms. There are two shorter (2.01 Å) and two longer (2.05 Å) Cr–O bond lengths. There are three inequivalent O sites. In the first O site, O is bonded in a distorted L-shaped geometry to one Cr and one O atom. The O–O bond length is 1.39 Å. In the second O site, O is bonded in a water-like geometry to two O atoms. The O–O bond length is 1.36 Å. In the third O site, O is bonded in a distorted L-shaped geometry to one Cr and one O atom.
