Abstract:
Abstract. The coordinating properties of a new bis(pyridylhydrazone)
ligand derived from iminodiacetic acid
diethyl ester and 2-pyridinecarboxaldehyde (picolinaldehyde)
H3Imdp and of the bis(salicylhydrazone) H5Imds and
H4MeImds ligands derived, respectively, from iminodiacetic
acid diethyl ester and from methyl-iminodiacetic
acid diethyl ester and salicylaldehyde were considered, by
means of analytical and spectroscopic methods, towards
first row transition metal ions. These ligands showed various
coordination modes in complexation with Cu(II),
Co(II), Mn(II) and Zn(II) ions. In particular, we have
synthesized and characterized, by analytical, 1H NMR and
IR techniques, tri-, di- and mononuclear metal complexes
of formula Co3(HImdp)(NO3)42H2O, Cu3(HImdp)(NO3)4
C2H5OHH2O, Cu3(HImdp)Cl4, Zn2(H3Imdp)(ClO4)42H2O,
Co3(HImds)Cl2CH3OHH2O, Zn2(H3Imds)Cl22H2O, Co-
(H4Imds)NO32H2O, Mn(H4Imds)ClCH3OHH2O, Cu(H3-
Imds)CH3OHH2O and Cu(H2MeImds).CH3OH3H2O.
