Abstract

Ba2Cu3O4Br2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to four equivalent O2- and four equivalent Br1- atoms. All Ba–O bond lengths are 2.84 Å. All Ba–Br bond lengths are 3.32 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 1.98 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 1.91 Å. O2- is bonded to two equivalent Ba2+ and three Cu2+ atoms to form distorted OBa2Cu3 trigonal bipyramids that share corners with eight equivalent BrBa4 tetrahedra, corners with three equivalent OBa2Cu3 trigonal bipyramids, edges with three equivalent OBa2Cu3 trigonal bipyramids, and faces with two equivalent OBa2Cu3 trigonal bipyramids. Br1- is bonded to four equivalent Ba2+ atoms to form BrBa4 tetrahedra that share corners with four equivalent BrBa4 tetrahedra, corners with sixteen equivalent OBa2Cu3 trigonal bipyramids, and edges with four equivalent BrBa4 tetrahedra.
