On Oxocuprates. XIX. The Oxohalogenocuprate(I): Ba₂CuO₂Cl The hitherto unknown compound Ba₂CuO₂Cl was prepared and examined by single crystal X-ray diffractometer investigation (a = 983.5 pm, α = 25,04°; Space group D⁵_3d? R3 m). Cu⁺ has the coordination O? Cu? O, Ba²⁺ an octahedral surrounding. A discussion of the structure is given.
