We have found that 'Hg2Cl2' can be intercalated into Bi2Sr2Can-1CunOz (n = -3 superconductors. Intercalated phases were examined by X-ray powder diffraction, electron diffractions, energy dispersive X-ray (EDX) analysis and magnetometry. The expansion along the c-axis upon interaction was estimated to be about 3.5Å for n = 1-3 specimens. The presence of both Hg and Cl atoms was confirmed by EDX analysis. The intercalated phase with tetragonal symmetry of n = 1 has a superstructure of three times the peroskite unit along the a-axis, and has kept the staggered stacking of the basic building blocks of the host sample. The superconductivity of the n = 2 phase is also described.
