Copper(II) complexes with the commercial auxin herbicides 2,4-dichlorophenoxyacetic acid (2,4D; C8H6O3Cl2) and 2-(2,4-dichlorophenoxy)-propionic acid (2,4DP;C9H8O3Cl2) were prepared and characterized. On the basis of the results of elemental analysis and Cu(II) determination, the following molecular formulae were proposed for the obtained compounds: Cu(C8H5O3Cl2)2.4H2O (Cu-2,4D) and Cu(C9H7O3Cl2)2.H2O (Cu-2,4DP).Water solubility of synthesized complexes at room temperature was determined. The complexes have been characterized by IR, VIS and EPR spectroscopy, conductivity (in methanol and dimethyloformamide), magnetic measurements and X-ray diffraction analysis. Thermal decomposition of these compounds in air was studied by TG, DTG, DTAand TG/MS methods with simultaneous analysis of the solid and gaseous products.
