The preparation and crystal structures of anhydrous KFeCl 3 and KFeBr 3 are described. X‐ray diffraction data obtained at room temperature indicate that the two compounds belong to the orthorhombic system, space group Pnma and z = 4. Unit cell parameters are a = 8.712 Å, b = 3.845 Å, c = 14.15 Å for KFeCl 3 and a = 9.220 Å, b = 4.026 Å, c = 14.899 Å for KFeBr 3 . Atomic positions were determined.
