Summary
In the most basic part of the binary system BaO−CuO two new compounds were identified corresponding to the Ba2CuO3 and Ba3CuO4 formulae. Another more oxidized phase of composition Ba2CuO3+δ was also obtained, which can exist in two crystalline modifications. For all these new substances the structural type and the lattice parameters are reported.
