Materials Data on Sr2Cu3(ClO2)2 by Materials Project
Sr2Cu3O4Cl2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to four equivalent O2- and four equivalent Cl1- atoms. All Sr–O bond lengths are 2.64 Å. All Sr–Cl bond lengths are 3.10 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.95 Å. In the second Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.94 Å. O2- is bonded to two equivalent Sr2+ and three Cu2+ atoms to form a mixture of distorted corner, edge, and face-sharing OSr2Cu3 trigonal bipyramids. Cl1- is bonded in a 4-coordinate geometry to four equivalent Sr2+ atoms.
