| Abstract: | The Stoichiometry of thermal decomposition was studied for the following compounds: Ni(NCS)2(pip)4 (I), (pip=piperidine), Ni(NCS)2(pip)2py·H2O (II), (py=piridine), Ni(NCS)2(4-Mepip)3 (III), Ni(NCS)2(3-Mepip)3 (IV) and Ni(NCS)2(3.5-Me2pip)3 (V). In complexes I, II, III and IV the loss of the volatile ligands (on the TG curve to 300 °C) occurs in three steps and in complex V in two steps. The loss of the last molecules of volatile ligands is accompanied by the decomposition of NCS groups. Spectral data and magnetic moment values for the initial complexes I and II (together with the defined intermediates) indicated pseudooctahedral configuration while pentacoordination for complexes III, IV and V. Structural changes of the complexes studied in thermal decomposition reactions are discussed. |
