Аннотация
The new complexes of 2-[(2-oxo-1,2-dihydroindol-3-ylidene)amino]butanoic acid, LH (where L = C12H11N2O3), with Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) of general formulae MLCl·nH2O, for Co(II), Ni(II) and Cu(II), and ML2·H2O for Mn(II) and Zn(II), where n = 1, 2 depending on M(II) ions, are synthesized. The complexes crystallize in a monoclinic system, and upon heating in the air (293–1173 K) decompose in three steps forming eventually the corresponding oxides of the metals(II). In the course of this process the organic ligand decomposes releasing the molecules of H2O, CO2, NH3, CO, hydrocarbons, and additionally HCl for Co(II), Ni(II) and Cu(II) complexes. Magnetic moments of compounds are determined in the ranges of 76–303 and 2–300 K. All analyzed compounds, except that of Zn(II), demonstrate the paramagnetic properties with the ferro- and antiferromagnetic interactions between molecular centres.
