We synthesized monodisperse nanospheres of an intermetallic FeSn5 phase via a nanocrystal-conversion protocol using preformed Sn nanospheres as templates. This tetragonal phase in P4/mcc space group, along with the defect structure Fe0.74Sn5 of our nanospheres, has been resolved by synchrotron X-ray...
