A new series of superconducting mercury-based layered cuprates has been synthesized. X-ray diffraction indicates that the compounds with formula Hg{sub 0.8}W{sub 0.2}Sr{sub 2}Y{sub 1{minus}x}Ca{sub x}Cu{sub 2}O{sub 6+{delta}} (0.3{<=}x{<=}0.6) exhibit the 1212 structure with space group P{sub 4/mmm}. The investigation of superconductivity determined by electrical resistance measurement shows that the superconducting transition temperature (T{sub c}, onset) of Hg{sub 0.8}W{sub 0.2}Sr{sub 2}Y{sub 0.4}Ca{sub 0.6}Cu{sub 2}O{sub 6+{delta}} is up to 94 K.
