Preparation and thermal decomposition of copper(II) complexes with 4-methylemidazole
Simple and mixed compounds of the formulae Cu(4-Meim)2, CuSal(4-Meim), CuSal(4-Meim)2 and CuSalox(4-Meim)2, where 4-Meim=4-methylimidazole, Sal=(OC6H4COO)2-, Salox=(OC6H4CHNO)2- have been prepared. Thermal decomposition reactions have been established on the basis of thermal and X-ray analyses of these compounds. The pyrolysis proceeds in several (3-4) stages connected with the mass loss and exothermic effects. As a result of the last stage of decomposition CuO is formed.
USE OF CRYSTALLINE FORMS OF COPPER SALICYLATE FOR THE CONTROL OF HYTOPATHOGENIC BACTERIA
The use is described of crystalline forms of copper salicylate with a molar ratio between copper and salicylic acid of (1:1), selected from crystalline form I, crystalline form II or crystalline form III and/or mixtures thereof, and the relative agronomic compositions for the control of phytopathogenic bacteria.

Thermal investigation of the compounds of the copper(II) mono(o-hydroxybenzoate) with chelate ligands
Heteroligand complexes of copper(II) were obtained as a result of the reaction of Cu(II) mono (o-hydroxybenzoate) (monohydrate) with 8-hydroxyquinoline (HOx), o-aminophenol (NH2Ph) and 2,2'-dipyridyl (2,2'-dipy). The mixture of the mono compound with: Cu(II) di(o-aminobenzoate) or Cu(II) di(o-hydroxybenzaldoximate) were obtained by the reaction with o-aminobenzoic acid (H2A) and o-hydroxybenzaldoxime (H2Salox). The obtained compounds and their sinters were subjected to chemical, X-ray and thermal analyses.
