A new series of Brønsted–Lewis acidic diethyldisulfoammonium chlorometallates, [DEDSA][FeCl 4 ] and [DEDSA] 2 [Zn 2 Cl 6 ], were synthesized as solid materials from the reaction of [(Et) 2 N(SO 3 H) 2 ][Cl] ionic liquid with transition metal chlorides (FeCl 3 and ZnCl 2 ) at 80 °C in neat condition for 2 h. The chlorometallates were fully characterized using various spectroscopic and analytical techniques such as Fourier transform infrared, UV–visible and Raman spectroscopies, powder X‐ray diffraction, scanning electron microscopy, energy‐dispersive X‐ray and thermogravimetric analyses, Hammett acidity and elemental analyses. Their catalytic activity was studied as reusable heterogeneous catalysts for the three‐component synthesis of novel 14‐aryl‐7‐( N ‐phenyl)‐14 H ‐dibenzo[ a , j ]acridines under solvent‐free conditions at 100 °C.
