Materials Data on TlCr(SO10)2 by Materials Project
TlCrO12(SO4)2 crystallizes in the cubic Pa-3 space group. The structure is zero-dimensional and consists of eight sulfuric acid molecules, four thallium molecules, and four CrO12 clusters. In each CrO12 cluster, Cr is bonded in an octahedral geometry to six equivalent O atoms. All Cr–O bond lengths are 2.09 Å. There are two inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Cr and one O atom. The O–O bond length is 1.26 Å. In the second O site, O is bonded in a single-bond geometry to one O atom.
