The copper-based rare-earth perovskites La1–xNdxCuO3(0≤x≤1) have been synthesized in the two-stage Walker-type high-pressure apparatus. The refined crystal structure results revealed that La1–xNdxCuO3 (0≤x≤0.4) adopts a rhombohedral structure with the space group $R\overline 3 c $. When 0.5≤x≤0.7, a mixed phase with both $R\overline 3 c $ rhombohedral and Pnma orthorhombic structures was observed in the system. With a further increase in Nd3+ doping, the system exhibits a single Pnma orthorhombic phase when x=0.8, 0.9 and 1. A comprehensive structural phase diagram of La1–xNdxCuO3 (0≤x≤1) was established in this study, providing a new material platform for investigating the magnetic properties, metal-insulator transitions, and other physical property evolutions in rare-earth 3d transition metal oxides.
