Resumo: | |||||||||||||
Compartmental ligands are those that have two or more polydentate
coordination sites close together , which can provide good recognition of metal ions
in their adjacent chambers. In this context, the BPMAMFF {3 N N bis(2
pyridylmethyl)aminomethyl] 5 methylsalicylaldehyde} ligand and its analog ue,
namely HBPAMFF {3 N N --(2 pyridylmethyl)(2 hydroxybenzyl)aminomethyl]
5 methylsalicylaldehyde}, are compartmental ligands whose reactivity features
highlight them as compou nds of interest for Materials Chemistry, Nanotechnology,
Bioinorganic Chemistry and other areas. In this work, BPMAMFF and HBPAMFF
were synthesized, as well as their respective oximic derivatives BPMAMFF ox
and HBPAMFF ox , since the addition of th is group can potentiate some of their
properties. Thus, 4 compartmental ligands were obtained, which were characterized
through their melting points, vibrational IR spectroscopy and 1 H NMR.
Furthermore , 6 coordination complexes, 5 of them new , were prepared from th ese
ligands, being the copper(II) complexes obtained for all of them and the zinc(II)
complexes synthesized only for BPMA derivatives. All coordination compounds
were characterized in the solid state by vibrational IR spectroscopy,
thermogravimetry and, wh en possible, by X ray diffraction in single crystals.
Zinc(II) diamagnetic complexes were also studied by 1 H NMR. The results
presented here in show that the oximic moiety , unlike what was expected at the
beginning of the project, does not participate in th e coordination of these metal ions
in the mononuclear species, thus becoming available for the coordination of other
metal centers. Hence , the se complexes can be used as building blocks in the
synthesis of supramolecular structures and coordination polymer s with the most
diverse applications. Finally, the obtention of the novel complex [Cu(
HBPAMFF )Cl 2 ]·0.25 H 2 O, in which it was observed, for the first time, that
the terminal phenol of the tripodal ligand HBPAMFF does not actively participate
in coordination, was described by us in a p a per published in the Journal of Molecular Structure.
