Supramolecular assembly of new heteropolymetalic molecules based on tetraiminodiphenolate macrocycle and hexacyanometallate anions: Magnetostructural and spectroscopic properties

New complexes of Ni(II) and Cu(II) with tridentate ONO Schiff base ligand: synthesis, crystal structures, electrochemical and theoretical investigation

“…They are able to coordinate metals through imine nitrogen and another group, more often than not, linked to aldehyde or ketone [4]. Schiff base metal complexes also find diverse and fruitful applications in industry and daily life [5][6][7][8][9][10]. There exist myriad reports on the biological activities of Schiff base ligands and their metal complexes, including their use for enzyme modeling, and catalytic activity and their function as antimicrobial, antifungal and antitumor agents [11][12][13][14][15].…”

Syntheses, crystallographic, mass-spectroscopic determination and antioxidant studies of Co(II), Ni(II) and Cu(II) complexes of a new imidazol based Schiff base

“…As an expected result of this, Schiff base metal complexes found diverse and fruitful applications in industry and daily life [5][6][7][8][9][10][11][12][13][14][15][16][17]. Within these privileged class of compounds, the synthesis of aromatic Schiff bases from both aromatic aldehyde and aromatic amine precursors are the most challenging route for synthetic chemists because of resulting in higher yield and purity than aliphatic ones based on the strength of relative stability of imine bonds conferred by electron-rich aryl side groups on the nitrogen and carbon atoms.…”

Synthesis, Structural and Spectroscopic Characterization of a New Coordination Polymer Based on a Tetraiminodiphenolate Macrocycle and Piperazine: [{Cu2(tidf)(µ-ppz)}(ClO4)2]n

“…Results show a very interesting case of self-assembly of building molecules into extended structures in the solid state [7]. In this work, continuing our general interest in the synthesis of metal complexes of the tetraminodiphenolate macrocycle ligand (Scheme 1), we report the preparation and characterization of a new coordination polymer based on a dicopper macrocycle complex and piperazine as building blocks.…”

“…The copper(II) ions are out of the equatorial plane, as indicated by the mean deviations from the least-square planes N1N2O1O1 i (i = -x, -y ? 1, -z-1) at 0.2040 (12) are linked by a hexacyanoferrate(II) ion through two cyano-bridges in a trans configuration and the unit cell revealed a complex supramolecular structure sustained by hydrogen-bond interactions between the metallo-complex and the crystallization water molecules [7].…”

“…Robson-type ligands, obtained from condensation of 2,6-diformyl-4-methylphenol and diamines, have been investigated over the years as their coordination compounds show interesting magnetic, redox and structural properties [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. This category of macrocycle is appealing because it can bind two metal ions simultaneously allowing the preparation of homometallic and heterometallic compounds.…”
