The structure and composition of the synthesized precursors containing amino and imino hydrochlorides substituted were studied by IR, NMR spectroscopy, elemental analysis and LUMOS microscope. On the basis of NMR analysis result was established that, THF molecule which used as a solvent in the synthesis of 2-substituted zirconium complexes remaining in the complex in shape of coordinated to the central atom. With LUMOS microscope was determined that synthesized complexes have a uniform composition
