| Abstract: | Syntheses of the dinuclear complexes [Co(C23H18N2O2)]2
(1), [Cu(C23H18N2O2)]2.H2O
(2), [Ni(C23H18N2O2)]2
(3), [Zn(C23H18N2O2)]2
(4) and [Cd(C23H18N2O2)]2
(5) containing the Schiff base ligand N,N′-bis(2-hydroxybenzilidene)-2,4,6-trimethylbenzene-1,3-diamine have been described. The complexes under investigation have been
characterized
by elemental analyses, IR, NMR (1H, 13C),
electronic absorption, emission and EPR spectral studies. The structure of
(1) has been determined by X-ray
single crystal analyses. Variable temperature magnetic susceptibility
measurements on
(1) and (2) reveal that the former displays antiferromagnetic coupling (J = -0.21 ± 0.1 cm-1), while the latter exhibits ferromagnetic
coupling (J = + 1.23 ± 0.1 cm-1). |
