We have synthesized new intercalation compounds of (HgX[sub 2])[sub 0.5]Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub y] (X = Br and I) and confirmed superconducting behavior for these compounds. Furthermore, it was found that the intercalation of HgX[sub 2] into Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub y] does not alter the hole carrier concentration on the CuO[sub 2] layers to any significant degree, and despite the large lattice expansion along the c-axis, the superconducting transition temperature drops only by a small fraction, indicating that at least the effect of interblock electronic coupling may be negligible in this system. In order to clarify the superconducting properties, XANES and EXAFS studies are under way. 18 refs., 3 figs.
