Higher superconducting transition temperature Tc is achieved in longer Cu-Cu bond distance samples. In this study, indium-based cuprate compounds with long Cu-Cu bond distance were prepared via solid-state reaction. The parent compound InBa2CuO4.44 is not electrically conducting due to the lack of oxygen ions in the CuO2 layer. In order to make it conducting, the oxygen content should be increased. For this purpose, polycrystalline InBa2-xLaxCuOy samples were prepared. In case of x = 1.0, single-phase compounds were prepared. Unfortunately, it is not superconductor but semiconductor.
