New intercalation superconductors of Lix(C2H8N2)yTiSe2 and Lix(C6H16N2)yTiSe2 with Tc = 4.2 K have successfully been synthesized via the co-intercalation of lithium and ethylenediamine or hexamethylenediamine into 1T-TiSe2. Moreover, it has been found that both intercalation compounds of LixTiSe2 and (C2H8N2)yTiSe2 also show superconductivity with Tc = 2.4 and 2.8 K, respectively. These results indicate that both the electron doping due to the intercalation of lithium and the expansion of the interlayer spacing between TiSe2 layers due to the intercalation of diamines suppress the charge density wave in 1T-TiSe2, leading to the appearance of superconductivity.
