Abstract: Methods of synthesis of new complex compounds of chloride and bromide of copper(II) with 2,3,5-triphenyltetrazolium chloride (LCl) with composition L2[CuCl4] (I) and L2[CuBr4] (II), have been developed for an acidic medium. The compounds were investigated by TGA, DSC, and IR spectroscopy. Their crystal structures were determined by XRD. The effect of copper(II) compounds on the germination of tomato seeds have been studied. The study has shown that complex I manifests the properties of the retardant of plant growth.
