Materials Data on CuBi2Se2O by Materials Project
CuSe2Bi2O is alpha Niobium phosphide-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Bi2O cluster and one CuSe2 cluster. In the Bi2O cluster, Bi+2.50+ is bonded in a single-bond geometry to one O2- atom. The Bi–O bond length is 2.08 Å. O2- is bonded in a linear geometry to two equivalent Bi+2.50+ atoms. In the CuSe2 cluster, Cu1+ is bonded in a linear geometry to two equivalent Se2- atoms. Both Cu–Se bond lengths are 2.27 Å. Se2- is bonded in a distorted single-bond geometry to one Cu1+ atom.
