“BaCuO 2 ” is not a simple ternary oxide but a complex oxocarbonate. It is a common component of superconducting oxocuprates. The complete elucidation of the structure by simultaneous X‐ray and neutron powder diffraction on samples of “BaCuO 2 ” gave a statistically disordered carbonate group at the heart of the structure and resulted in the composition of this supposed oxide given in the title.
