Crystal structures in the Nd_1+xBa_2-xCu₃O_7-δ system have been investigated by X-ray powder diffraction combined with Rietveld analysis. The compound NdBa₂Cu₃O_7-δ is isomorphic with orthorhombic YBa₂Cu₃O_7-δ. With the increase of x the orthorhombic distortion decreases, and the compound becomes tetragonal at x=0.2. The tetragonal structure is isomorphic with the tetragonal form of YBa₂Cu₃O_7-δ. T_c of the compounds with x=0 and 0.05 is above 90 K, which decreases monotonically with x and the compound becomes semiconducting at x=0.4.
