TL;DR: The authors examined the structure of La2CuO4 at room temperature and found it to be an orthorhombic distortion of the K2NiF4 structure (a = 5.363 A, b = 4.409 A, c = 13.17 A).

TL;DR: In this article, the crystal chemistry of the oxides of the general formula A 2 B O 4 with particular reference to the stability of the K 2 NiF 4 structure and the relations between the different structures exhibited by this family of oxides is discussed.

TL;DR: In this article, two new copper III + compounds have been prepared under oxygen pressure and investigated, and the first phase LaCuO3 has a distorded rhomboedral perovskite structure (a = 5.431 ± 0.002 A ; α = 60°51′ ± 0°02′) and the second phase La2Li0.50Cu0.

TL;DR: In this paper, a new copper (+III) compound, SrLaCuO 4 has been prepared under oxygen pressure and investigated, and it has the K 2 NiF 4 structure (a = 3.765 ± 0.002 A c = 13.27 ±0.02 A).
