摘要：

The authors have prepared a new cuprate superconductor with Tc (onset)=50 K and a hitherto unreported double perovskite structure (1-2-1 phase) with alternating single copper octahedron sheets and single (Tl, Bi) sheets. This structure is closely related to those of the 4-2 phase (La1-xSrx)4Cu2O4+δ and the (semiconducting) 2-2-1 phase Bi2(Sr,Ca)2Cu1O6+δ.
