Classical tetradentate chelation and novel bis(bidentate) congregation motifs of a neutral N-donor Schiff base in dinuclear cadmium(II) complexes: Synthesis, structure and luminescence behaviour

Synthesis, characterization, electrochemical behavior and antibacterial/antifungal activities of [Cd(l)X2] complexes with a Schiff base ligand

“…1 The Schiff base compounds have a wide range of applications including their usage as dyes and pigments, catalysts, stabilizers of polymers, antibacterial, antifungal, anticancer, antimalarial, antivirus and herbicidal compounds. [12][13][14][15] Some other cadmium Schiff base complexes with the ligands 2-[3-(2-aminophenoxy) naphthalen-2-yloxy]benzenamine and a Schiff base derived from naphthofuran--2-carbohydrazide and cinnamaldehyde were found to show biological properties, such as antibacterial and antifungal activities. [9][10][11] Some Schiff base complexes of cadmium containing ligands such as 1,10-phenanthroline-2,9-dicarboxaldehyde-di-2-hydroxybenzoylhydrazone, (E)-2-((pyridin-2-yl)methyleneamino) benzoic acid and N,N′-(bis(pyridine-2yl)benzylidene)-1,4-butanediamine possessing various properties, such as structural and chemo-luminescence, have been reported in the literature.…”

Synthesis, Characterization, and Crystal Structure of a Dinuclear Cadmium(II) Complex Derived From 4-Chloro-2-{[2-(2-Hydroxyethylamino)Ethylimino]Methyl}Phenol

“…[2,3] Cadmium complexes with Schiff bases derived from salicylaldehyde and its derivatives have been received much attention in coordination chemistry due to their interesting structures and properties. [4][5][6][7][8] A number of the dinuclear cadmium(II) complexes were prepared with the macrocyclic Schiff bases. [9][10][11][12][13] However, those with the asymmetric tri-or tetradentate Schiff bases are relatively rare.…”

Syntheses, molecular and crystalline architectures, and luminescence behaviours of two dinuclear cadmium(II) compounds containing a tetradentate N-donor di-Schiff base

“…The larger-sized pseudohalide, dicyanamide (dca), is a versatile [21][22][23][24] bridging unit and may bind metal ion through terminal or bridges such as l 1,1, l 1,3, l 1,5 , l 1,1,5, l 1,3,5 , l 3,3,5 and l 1,3,3,5 motifs. Recently, we are active [25][26][27][28] to isolate cadmium(II) compounds of varied molecular and crystalline architectures and with interesting molecular properties using multidentate N-donor organic di-Schiff bases and polyamines. In our present endeavor, we have taken a tetradentate di-Schiff base N,N 0 -(bis(pyridin-2-yl)benzylidene)-1,3-propanediamine (L) (Scheme 1) to synthesize cadmium(II) compounds of different geometries and molecular properties in combination with bridging units like chloride and dicyanamide.…”
