Abstract

This study manufactured and described new organic salts containing (benzylcarabazoliumchloride) and (benzyltriphenylphosphonium) ligands, which were prepared and synthesized and then interacted with some transition metals (Cr(III), Co(II), Ni(II), Cu(II), and Zn(II)). Obtained complexes were characterized by element analysis, FTIR (Fourier change infrared) and UV-vis spectral investigation, magnetic measurement, conduction measurement, and 1H-NMR for the ligands. The stoichiometry of the complexes was determined based on input to be (1:2) and (1:3) for metal-to-ligand ratio. The conductivity results suggest that these complexes are electrolytes. Furthermore, the electronic spectra and magnetic measurements provide insights into the nature of these composites. [bCar]2[MCl4] and [bTpp]2[MCl4] have a tetrahedral environment, while [bCar]3[CrCl6] and [bTpp]3[CrCl6] have an octahedral environment around the metal ions.
