Base stable benzonitrile was reacted with tert-butyl arsenic dilithium in tetrahydrofuran. Crystallization of the product was performed in tetramethylethylenediamine and dimethyldiglycol. The resulted aromatic five–membered diaza cycle containing arsenic was coordinated in salt form and characterized using NMR and FT–IR spectroscopy, Mass spectrometry and single crystal structure analysis. According to the result of analysis, the crystallized product consists of distorted octahedrally coordinated Li+ ion, [Li(MeO(CH2)2O(CH2)2OMe)2]+, and the complex anion [Li(Me2N(CH2)2NMe2){As[NC(C6H5)NC(C6H5)]}2]– with a distorted tetrahedrally environment of the Li+ ion.
