Systematics in the superconducting behaviour of Ln2-xSrx(Bax)CuO4, La2-xSrx-yBay(Cay)CuO4, (La1-xLnx)2-ySry(Bay)CuO4 with Ln = Pr, Nd or Y and related systems are presented. The role of oxygen stoichiometry and lattice parameters of these mixed valent copper oxides is indicated. These high Tc superconducting oxides exhibit high-temperature resistivities in the borderline of the metal-nonmetal transition.
