Description / Table of Contents:
Zusammenfassung Es wurde eine Reihe Mischligandenkomplexe von Co(II), Ni(II), Cu(II) und Zn(II) der allgemeinen FormelM(IM)(L)·H2O (mit H2IM = Iminodiessigsäure undL = 2,2′-Bipyridyl und o-Phenanthrolin) wurden untersucht und in reinem Zustand isoliert. Die Charakterisierung der Metallchelate erfolgte mittels Elementaranalyse, IR- und Elektronenspektroskopie sowie durch Konduktivitäts- und magnetische Messungen.
Notes:
Abstract A series of mixed-ligand complexes of Co(II), Ni(II), Cu(II) and Zn(II) with general formulaM(IM)(L)·H2O, where H2IM=iminodiacetic acid;L=2,2′-bipyridyl ando-phenanthroline, have been studied and isolated in pure state. The metal chelates have been characterized by elemental analysis, IR and electronic spectra, conductivity and magnetic measurements. The octahedral environment around the metal ion has been proposed. The thermal properties of metal complexes in solid state have been studied under non-isothermal condition in nitrogen atmosphere by simultaneous TG and DTA. TG and DTA curves show that the decomposition took place in two steps. Thermodynamic parameters such as activation energy,E, order of reaction,n, entropy of activation, ΔS
