摘要
The compounds ML2(NCS)(2), (M(II)=Mn, Co), FeL2(NCS)(2). 2H(2)O, NiL3(NCS)(2). 3H(2)O (L=2,2'-bipyridine, 2-bipy) MX2(NCS)(2). 2H(2)O (M(II)=Mn, Fe; X=4,4'-bipyridine, 4-bipy) have been prepared and their IR spectra and molar conductivity studied. The thermal decomposition of the complexes was studied under non-isothermal conditions in air. During heating the hydrated complexes lose crystallization water molecules in one or two steps and then decompose via different intermediate compounds to the oxides Mn3O4, Fe2O3, CoO, NiO.
