N2 - We report superconductivity in novel iron-based compounds Ca 10(PtnAs8)(Fe2-xPt xAs2)5 with n = 3 and 4. Both compounds crystallize in triclinic structures (space group PĪ), in which Fe 2As2 layers alternate with PtnAs8 spacer layers. Superconductivity with a transition temperature of 38 K is observed in the n = 4 compound with a Pt content of x ∼ 0.36 in the Fe2As2 layers. The compound with n - 3 exhibits superconductivity at 13 K.
