摘要：
A new blocking layer with an a-axis length of 4.18 Angstrom, BaInOy, was found. The blocking layer supplies an apical oxygen to the CuO2 layer and produces an oxygen vacancy in the in-plane of the CuO2 layer. By matching the blocking layer with the CuO2 layer, a new layered cuprate, Ba2InCuO4.53, was prepared. Its space group was Pmmm with lattice parameters of a = 4.1820(6) Angstrom, b = 4.1820(5) Angstrom and c = 8.0889(9) Angstrom. The fact that the a- and b-axis lengths of Ba2InCuO4.53 compound are much longer than those of the other cuprate compounds is explained by the existence of an oxygen vacancy in the CuO2 Its resistivity at room temperature was as large as 28.8 M Omega cm. The insulating property probably comes from the existence of the oxygen vacancy in the CuO2 layer.
