We have studied as-synthesized, vacuum-annealed and high-pressure oxygen annealed HgBa2CuO4+6 (Hg-1201 ) using Raman scattering. The apical-oxygen vibrational frequencies showed a slight but systematic shift (590, 591 and 587 era-t ), in agreement with the slight change in the Hg--O bond length from

The new Hg-based superconductor HgBa2CuO4+a has been studied with scanning electron microscopy, high-resolution electron microscopy and energy dispersive spectrometry analysis. The diffraction patterns confirmed the primitive unit cell obtained from X-ray powder data (space group P4/mmm, a= 3.8797(5
