✦ Synopsis

18+δ (1 ≤ x ≤ 2) having the tetragonal structure of an anion-deficient perovskite. Its crystal structure is refined according to the Rietveld method in space group P4b2. The formation of the compound is attributed to the stabilizing effects of the Ni atoms. The tendency of the Ni atoms to prefer an octahedral environment results in the formation of the unusual crystal lattice of this phase. Studies on the thermal behavior of the cuprate are described.
