Two new tetrachloroferrates(III) have been synthesized of molecular formulas [(CH 3 ) 2 NH 2 ][FeCl 4 ] and [(CH 3 ) 2 NH 2 ] 2 FeCl 5 . The differences in their physicochemical properties have been highlighted using thermal analysis (TG‐MS) and differential scanning calorimetry (DSC). The crystal and molecular structure of [(CH 3 ) 2 NH] 2 FeCl 5 was determined. The iron(III) cation is four coordinated by chloride ions, and it adopts a slightly distorted tetrahedral coordination with three angles smaller and three larger than the tetrahedral one. In the structure four intermolecular N‐H···Cl hydrogen bonds link the [(CH 3 ) 2 NH 2 ] + cations to dimers via a Cl − bridge.
