Materials Data on Ba2CuTe2F by Materials Project
Ba2CuTe2F crystallizes in the tetragonal P4/mmm space group. The structure is one-dimensional and consists of one Ba2CuTe2F ribbon oriented in the (0, 0, 1) direction. Ba2+ is bonded in a distorted linear geometry to one Te2- and one F1- atom. The Ba–Te bond length is 3.27 Å. The Ba–F bond length is 2.45 Å. Cu1+ is bonded in a linear geometry to two equivalent Te2- atoms. Both Cu–Te bond lengths are 2.42 Å. Te2- is bonded in a linear geometry to one Ba2+ and one Cu1+ atom. F1- is bonded in a linear geometry to two equivalent Ba2+ atoms.
