The synthesis and properties of manganese(II) complexes with the commercial auxin herbicides: 2,4-dichlorophenoxyacetic acid (2,4D; C8H6O3Cl2) and 2-(2,4-dichlorophenoxy)- propionic acid (2,4DP; C9H8O3Cl2) are reported. On the basis of the results of elemental analysis and Mn(II) determination, the following molecular formulae were proposed for the obtained compounds: Mn(C8H5O3Cl2)2.2H2O (Mn-2,4D) and Mn(C9H7O3Cl2)2.2H2O (Mn-2,4DP). X-ray powder analysis was carried out. The water solubility of the synthesized complexes at room temperature was determined. The IR spectra, conductivity data (in methanol and dimethylformamide), variable temperature magnetic susceptibility and the way of Mn-herbicide coordination are discussed. Thermal decomposition of these complexes in air was studied by TG, DTG, DTAand TG/MS methods with simultaneous analysis of the solid and gaseous products of pyrolysis.
