Abstract

The observation of superconductivity at 4.3 K in a new crystalline form of Na _0.3CoO ₂·1.3H ₂O is reported. The new superconductor has three layers of CoO ₆ octahedral per crystallographic unit cell, in contrast to the previously reported two-layer superconductor. The three-layer cell occurs because the relative orientations of neighboring CoO ₂ layers are distinctly different from what is seen in the two-layer superconducting phase. This type of structural difference in materials that are otherwise chemically and structurally identical is not possible to attain on the layered copper oxide superconductors. The synthesis and stability of the new phase are described.
