Abstract

A new compound, Y_2.0Sr_5.0Cu_6.0C_0.9O_16.2, was prepared at 1273 K under an atmosphere of O₂CO₂ (partial pressure of CO₂:P_CO2=0.010 MPa). The X-ray powder diffraction pattern of the compound could be characterized by tetragonal symmetry (a=3.848, c=11.185 A ̊). This new compound may have a structure related to that of YBa₂Cu₃O_7-y (123). Assuming the 123 structure, the structural formula of this new compound is described as (Y_0.86Sr_0.14)Sr₂(C_0.4Cu_0.6)Cu₂O₇. The density of 5.48 g/cm³ calculated from this formula agreed with the observed density (5.6 g/cm³).
