Targeted syntheses of homo- and heterotrinuclear complexes involving MII-NiII-MII (M = Ni, Cu, and Pd) nonlinear core: Structure, spectroscopy, magnetic and redox studies

Résumé

Homo- and heterotrinuclear complexes [LNi{M(Ln)}2](ClO4)2 H2O involving NiIIMII 2 nonlinear cores (M = Ni, Cu, and Pd) (1-6) have been synthesized by a single-pot reaction when the oximato metal complexes [MLn(H2O)]ClO4 (HLn are tridentate oxime ligands), prepared in situ in methanol are allowed to react with the precursor nickel(II) complex [LNi(H2O)2] (H2L = N,N0-dimethyl-N,N0-bis(2-hydroxy-3,5- dimethylbenzyl)ethylenediamine). Single crystal X-ray diffraction analysis, and ESI-MS spectroscopy have been used to establish their identities which involve an octahedral Ni(II) site flunked by two metal-oximate moieties, each in a square planar environment. The electronic and molecular structures of these compounds are interesting due to a synergistic bonding mechanism operative through the deprotonated oxime and the phenolate oxygen atoms via the metal centers........
