Abstract: Sixteen new inorganic-organic hybrid compounds of 1,3-dialkyl-2-(arylazo)imidazolium, [RaaiR/R//]+ (R, alkyl group), and I- or [CdI4]2- as counter ion are synthesized and characterized by spectroscopic (IR, UV-vis, 1H NMR) techniques. The single crystal X-ray diffraction studies of representative compounds, viz., 1,3-dimethyl-2-(p-tolylazo)imidazolium iodide [MeaaiMe2+]I- and bis- [1-methyl-3-benzyl-2-(p-tolylazo)imidazolium]tetraiodocadmium(II) [Meaai(Me)CH2Ph+]2 [CdI4]2-, have confirmed the proposed structures. DFT computation has been used to explain the electronic structure and the electronic spectra of the compounds.
