| Abstract: | Two new tetrachloroferrates(III) have been synthesized of molecular formulas (CH3)2NH2]FeCl4] and (CH3)2NH2]2FeCl5. 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 (CH3)2NH]2FeCl5 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 (CH3)2NH2]+ cations to dimers via a Cl? bridge. |
