摘要：

The title superconductor with T(c) of 110 K was prepared at 1200-degrees-C under high pressure of 6 GPa. X-ray powder diffraction and HRTEM observations indicated that the superconducting phase crystallizes in a tetragonal system with the space group, P4/mmm and lattice parameters, a = 3.8359(1), c = 17.082(2) angstrom. It is essentially isomorphous with the Tl(or Hg)-1234 phase.
