Nanostructures of FeSe x with a tetragonal PbO‐type phase have been grown through a new and simple solvothermal route. By adding polyvinyl pyrrolidone (PVP) as a controlling reagent, the products change from nanoflowers to regular square nanoplates. Both the phase and structure are identified by powder X‐ray diffraction and electron microscopy. The square nanoplates are revealed to be enclosed by two larger (001) planes and four equivalent smaller {100} side surfaces. The choice of the solvent is also important for the successful synthesis of the tetragonal PbO‐type phase. This growth approach is not only facile and mild, but is also more advantageous for obtaining uniform FeSe x nanocrystals over other methods reported previously.
