Materials Data on La2CuSe2O by Materials Project
La2CuSe2O crystallizes in the tetragonal P4/mmm space group. The structure is one-dimensional and consists of one La2CuSe2O ribbon oriented in the (0, 0, 1) direction. La+2.50+ is bonded in a linear geometry to one Se2- and one O2- atom. The La–Se bond length is 2.83 Å. The La–O bond length is 2.12 Å. Cu1+ is bonded in a linear geometry to two equivalent Se2- atoms. Both Cu–Se bond lengths are 2.22 Å. Se2- is bonded in a linear geometry to one La+2.50+ and one Cu1+ atom. O2- is bonded in a linear geometry to two equivalent La+2.50+ atoms.
