Abstract
Crystals with a stoichiometry either Ba2YCu3-x O7-y or Ba4YCu2O8-y are a high t c superconductor. The former is well known. With respect to the latter the crystal structure was determined to be tetragonal with lattice parameters a=5.78 Å and c=7.99 Å. It was found that both of them reacted with water. The former was slowly decomposed by warmed water at about 35°C, while the latter was destroyed at room temperature in an instant.Keywords
