Abstract
Abstract Ionic liquid based on benzotriazolium ions were synthesized. these ionic liquids were characterized by IR, UV, Conductivity measurements and elemented analysis. There ionic salts with Co+2, Ni+2,Cu+2 and Zn+2 of *correspondance authour the types [A]+2[MCl2I2] and [A`]+ [MCl2I2], where A= benzotriazolium cation+1, A` = benzotriazolium cation+2, M = Co+2, Ni+2, Cu+2 and Zn+2 were prepared and characterized by elemental analysis, molar conductance, IR, UV∕V is, metal content and magnetic measurements. The results of electronic spectra and magnetic measurements showed that the anions of the type [MCl2I2] have tetrahedral and square planer geometry around the metal ions.
