Polynuclear metal complexes of ligands containing phenolic units

Synthesis, structure and magnetic characterization of dinuclear copper(II) complexes of 2,6-bis[bis(pyridine-2-ylmethyl)aminomethyl]-4-methylphenol

“…The most common feature in these compounds is a phenolate group is deprotonated and bridged to two similar or different metal ions through the phenoxido group [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The presence of aliphatic (acetate, propionate) or aromatic carboxylate (benzoate and their substituents) resulted in the formation of doubly bridged dicarboxylato compounds [10][11][12][13][14][15][16].…”

“…In addition the complexes reveal efficient catalytic activity, particularly in hydrolytic reactions that involve hydrolysis of phosphodiester, DNA cleavage and carbonic hydratase and therefore, have been used to elucidate the reaction mechanism of some metalloenzymes [1][2][3][4][5][6][7][8]. This is due to the key role played by the phenolic group in such compounds such as (i) charge neutralization, (ii) bridging capability via the phenolic group, and (iii) great synthetic flexibility associated with the benzene ring [9]. Symmetric and asymmetric binucleating phenolic compounds containing two or four pendant arms have been launched and their corresponding dinuclear 3d metal(II) have been synthesized and characterized .…”

Structural characterization of ferromagnetic bridged-acetato and -dichlorido copper(II) complexes based on bicompartmental 4-t-butylphenol

“…The phenolic group in this class of binucleating compounds has the capability of bridging metal ions through the deprotonated (phenoxido group) or neutral phenolate [5]. This property led to the isolation and characterization of many dinuclear metal complexes [5][6][7]. In the presence of other bridging groups such as acetate, hydroxide, oxide and methoxide molecules of interesting structural features and magnetic properties were obtained [8,9].…”

Synthesis, Characterization and in vitro Cytotoxicity Studies of Pentadentate Ligand and its Copper(II) Complexes

“…Synthesis of ligand: 4-t-Butyl-2,6-bis(chloromethyl)phenol was treated with isonicotinic hydrazide in ethanol in 1:2 ratio [9,10]. A yellow solid was obtained, filtered and recrystallized in ethanol (Scheme-I).…”
