Versatile binding properties of a di-2-pyridyl ketone nicotinoylhydrazone ligand: Crystal structure of a Cu(II) complex

“…Mixed ligand metal complexes of hydrazones, have proved to be useful catalysts in reactions such as hydrogenation, oxidation, carbonylation and hydroformylation [2]. The applications of rhenium-carbonyl compounds as electrochemical sensors and the optosensing behavior of ruthenium(II), manganese(I) compounds of di-2-pyridyl ketone have been reported [3,4]. The use of these systems as molecular sensors is due to their high values of extinction coefficients and low values for their activation parameters.…”

The 1 H-NMR spectra measured in d 6 -dmso confirmed the symmetrical coordination of 3 -dpkO,OH as evident by the appearance of four peaks with the same intensity.…”

“…We have been interested in the chemistry of di-2-pyridyl ketone (dpk) and its oxime and hydrazone derivatives (see scheme 1), and reported on the synthesis, characterization and structures of a series of low-valent metal compounds of di-2-pyridyl ketone derivatives, and their applications as molecular sensors for metal ions and biomolecules that include monosaccharide [8][9][10][11][12][13][14][15][16][17][18][19]. The electrochemical reactions of fac-[Re(CO) 3 3 (dpk)Cl] as an electrochemical sensor for electrophiles [8,9].…”

Synthesis, and molecular sensing behavior of fac-[Re(CO)3(κ2-N,N-dpksc)Cl], dpksc=di-2-pyridyl ketone semicarbazone

“…In continuation of our efforts to explore the chemistry of di-2-pyridyl ketone derivatives, this report will describe the synthesis and physico-chemical properties of the first rhenium compound di-2-pyridyl ketone semicarbazone (see Scheme 1). In previous reports, we described the synthesis, spectroscopic, electrochemical, and solid state structures of a variety of metal compounds that contain di-2-pyridyl ketone derivatives [30][31][32][33][34][35][36][37]. Electrochemical reactions of CO 2 with fac-[Re(CO) 3 (dpk)Cl] measured on non-aqueous solvents showed strong solvent dependence and revealed metal-based and ligandbased reactivity [30].…”

“…Electrochemical reactions of CO 2 with fac-[Re(CO) 3 (dpk)Cl] measured on non-aqueous solvents showed strong solvent dependence and revealed metal-based and ligandbased reactivity [30]. Spectroscopic measurements done on nonaqueous solutions of di-2-pyridyl ketone hydrazones and their metal complexes show high sensitivity of these compounds to changes in their surroundings [32][33][34][35][36][37]. Solid state structures of a variety of di-2-pyridyl ketone derivatives and their metal compounds show strong solvent dependence due to solvent complex interaction and the presence of extensive network of hydrogen bond [33][34][35][36][37].…”
