Abstract: <span style="font-size:9.0pt;font-family: " times="" new="" roman";mso-fareast-font-family:"times="" roman";mso-ansi-language:="" en-us;mso-fareast-language:en-us;mso-bidi-language:ar-sa"="" lang="EN-US">Sixteen new inorganic-organic hybrid compounds of 1,3-dialkyl-2-(arylazo)imidazolium, [RaaiR<sup>/</sup>R<sup>//</sup>]<sup>+</sup> (R, alkyl group), and I<sup>-</sup> or [CdI<sub>4</sub>]<sup>2-</sup> as counter ion are synthesized and characterized by spectroscopic (IR, UV-vis, <sup>1</sup>H NMR) techniques. The single crystal X-ray diffraction studies of representative compounds, viz., 1,3-dimethyl-2-(<i style="mso-bidi-font-style:normal">p</i>-tolylazo)imidazolium iodide [MeaaiMe<sub>2</sub><sup>+</sup>]I<sup>-</sup> and bis- [1-methyl-3-benzyl-2-(<i style="mso-bidi-font-style:normal">p</i>-tolylazo)imidazolium]tetraiodocadmium(II) [Meaai(Me)CH<sub>2</sub>Ph<sup>+</sup>]<sub>2</sub> [CdI<sub>4</sub>]<sup>2-</sup>, have confirmed the proposed structures. DFT computation has been used to explain the electronic structure and the electronic spectra of the compounds.</span>
