A new iron-based superconductor Lix(C2H 8N2)yFe2-zSe2 with T c = 45K has successfully been synthesized via intercalation of dissolved lithium metal in ethylenediamine. The distance between neighboring Fe layers is 10.37 Å and much larger than those of FeSe with Tc = 8K and KxFe2Se2 with Tc ~ 30 K. It seems that the high-Tc of Lix(C2H 8N2)yFe2-zSe2 is caused by the possible two-dimensional electronic structure due to the large c-axis length.
