| Abstract: | The reaction of warm ethanolic solution of Ni(OAc)2 · 4 H2O with S-alkylisothiosemicarbazide-hydrogeniodide (L? R · HI; R = Me, Et, n-Pr, n-Bu) and pyridine yielded the octahedral bis(ligand) complexes of the general formula Ni(L? R)2Py2]I2. By the isothermal heating at 95 and 110°C, these complexes were transformed into the square-planar Ni(L? R)2]I2 (R = Me, Et) complexes and the Ni(L? R)2I2] (R = n-Pr, n-Bu) complexes of distorted octahedral configuration. Besides, the Zn(L? Me)2I2 complex was prepared. The compounds have been characterized by elemental analysis, magnetic measurements, diffuse reflectance spectra and TG analysis. |
