abstract

The complex compositions [CuL₂](Cl)₂,{[CuL](Cl)₂}n, [CuL₂]SO₄, {[CuL]SO₄}n, [CuL₂](OAc)₂, {[CuL](OAc)₂}n are synthesized with the help of interaction 2- [3- alkoxy- 4 –(hydroxy, alkoxy, acyloxy)phenyl-1H-benzimidazole derivatives of aldehydes of vanillin row - with сooper chloride (II), сooper sulfate (II), сooper acetate (II). The structure of the composites is proved with the help of UR- и NMR H1 spektra and the data of elementary analysis. The received complex have shown high fungicidal activity against Alternnaria alternata, Aspergillus niger, Botritis cinerea, Fusarium oxysporum, Monilia sp., Mucor sp., Penicillum lividum.
