Abstract: An extended molecular crystal model is put forward for the mechanism of high-temperature superconductivity in the typical perovskite-like structures Ba x La 2− x CuO 4 and Ba 2 YCu 3 O 6.5+1.5 x , 0 x ≲ 0.4. It is shown that the Jahn-Teller effect of the Cu 2+ cation brings about an attractive pairing interaction between the hybridized 3 d 9 electron states. The critical temperature is estimated and compared with the available experimental data.
