The family of iron arsenide superconductors is expanded by the new iron platinum compounds (CaFe1−xPtxAs10)Pt4−yAs8 with novel crystal structures. Layers of FeAs4/4 tetrahedra and of nearly planar PtAs4/2 squares with (As2)4− dumbbells are stacked in different ways, resulting in polytypes with triclinic or tetragonal symmetry. Superconductivity up to 35 K is induced either by Pt doping of the Fe site or by electron transfer from PtAs to FeAs layers.
