Abstract Three new oxycarbonate superconductors recently obtained in our laboratory are described. (1) Sr2CuO2(CO3)1−x (BO3) x (T c = 35 K) was synthesized under ambient pressure, providing a new method for carrier doping on the layered copper oxycarbonate system. (2) Ca n (Ca, Sr)2Cu n+1(CO3)O y (n = 1, 2, 3) was synthesized under high pressure. Superconductivity was achieved by substituting (BO3)3− for a part of (CO3)2−. (3) A new Hg system HgBa2Sr2Cu2(CO3)O6+δ was synthesized.T c obtained from the magnetic susceptibility is about 66 K.
