Today, the world is a decrease in agricultural crop productivity during global climate change and environmental problems. There is a growing need for effective chemical compounds that control the growth and increase the productivity of cultivated plants. Obtaining low-toxicity and high-efficiency stimulators that increase plant productivity and fight against various harmful insects and phytopathogenic microorganisms are essential issues in world agriculture. In the world, a lot of research is being conducted on the research of complex compounds with mixed ligands formed by mono- and dichlorophenoxyacetic acid derivatives and their d-metal salts, their composition, structure, and properties. In this regard, the synthesis of complex compounds of ligands based on highly conformationally mobile carboxylic acids with intermediate metals, exhibiting new structures and functions, the dependence of the structure of the formed complex compounds on various factors, including the nature of the metal, the presence of the ligand substituent, as well as the coordination of the ligand to the central ion, determining its nature and physicochemical and biological property is of great importance.
