Synthesis of molecular complexes of transition metals with ligands on the base of acetoacetic ether and acetylpinacolyn dihydrazones

摘要

Products of the condensation of dicarboxylic acid dihydrazides with acetoacetic ether and pinacolyn as well as their complexes with chlorides of the following transition metals: Cr(III), Co(II), Cu(II), Zn(II), described as M_2LCl_n (where M- metal atom, L -- ligand, n=2 or 4) have been synthesed and characterized by elemental analysis, IR and ~1H NMR spectroscopy methods. It was shown that ligand realized in eL. oxyazine form during the complex formation, and ligand appears as tetradental system with formation o[ binuclear molecular complexes of transition metal ions.
