Phosphatase-mimicking activity of a unique penta-nuclear zinc(ii) complex with a reduced Schiff base ligand: assessment of its ability to sense nitroaromatics

Abstract

A penta-nuclear zinc(ii) complex has been synthesized and characterized. The complex has shown good phosphatase-mimicking activity, which has been evaluated spectrophotometrically. The complex also behaves as a sensor for the detection of nitroaromatics via turn-off fluorescence response.

An insight into the non-covalent interactions in the solid state structures of dinuclear cobalt(ii) complexes with N,O-donor ligands: application of the complexes in the fabrication of Schottky devices

“…[21][22][23][24][25] The unusual physical properties of several di-and polynuclear complexes with salen-type Schiff base ligands and their reduced analogues and their ability to mimic the biological functions of different metalloproteins have attracted the interest of coordination chemists to synthesize, characterize and explore new complexes in salen and reduced salen families. [26][27][28][29] Additionally, multi-metallic complexes containing paramagnetic metal centers are important for their interesting magnetic properties and applications as magnetic materials. [30][31][32][33][34] Another leading area of modern research is the study of the opto-electronic properties of these complexes.…”

Synthesis and characterization of a mononuclear zinc(ii) Schiff base complex: on the importance of C–H⋯π interactions

“…[14][15][16][17] So, many zinc(II) complexes have been used for the detection of nitroaromatic explosives by turn off uorescence response. [18][19][20] The d 10 electronic conguration of zinc(II) also favours a variety of coordination geometries, e.g. tetrahedral, 21 square pyramidal, 22 octahedral, 23 trigonal prism, 24 trigonal dodecahedral 25 etc.…”

Importance of π-Interactions Involving Chelate Rings in Addition to the Tetrel Bonds in Crystal Engineering: A Combined Experimental and Theoretical Study on a Series of Hemi- and Holodirected Nickel(II)/Lead(II) Complexes

“…2,2-Dimethyl-1,3-diaminopropane was refluxed with 3-methoxysalicylaldehyde and 3-ethoxysalicylaldehyde in a 1:2 ratio respectively, followed by the addition of NaBH 4 to form two N 2 O 2 O′ 2 donor compartmental reduced Schiff bases (H 2 L 1 and H 2 L 2 ) following standard literature methods. − These ligands (H 2 L 1 and H 2 L 2 ) on reaction with different ratios of nickel­(II) and lead­(II) salts in different solvents produced the complexes. Formation of complexes 1 – 5 is shown in Scheme .…”
