Thermal, spectral, magnetic and antimicrobial behaviour of new Ni(II), Cu(II) and Zn(II) complexes with a hexaazamacrocyclic ligand

Synthesis, Crystal Structure, and Spectroscopic Properties of Cu(II) Complex with 14-Membered Hexaazamacrocyclic Ligands

“…The TGA curve indicated that the thermal decomposition of this complex involved elimination of perchlorate moiety and finally resulting in the formation of copper oxide [5,50,[54][55][56]. The first weight loss of 28.9 % (calculated 27.8 %) was in the range of 120-250°C corresponding to the loss of two perchlorate molecules.…”

“…Hexaazamacrocyclic complexes are of great importance with potential applications in antimicrobial activity [1,[3][4][5][6], photosynthesis [7], catalysis [8][9][10][11], gas sorption [12,13], and molecular magnetism [14][15][16][17][18]. Copper(II) and nickel(II) having received much attention because of their high thermodynamic stability and kinetic inertness can provide the possibility of synthetically convenient chemical modification of macrocyclic ligand using the template synthetic method [19].…”

“…In addition, formaldehyde can serve as a link for two amine moieties and, therefore, metal-directed reaction of coordinated amines and formaldehyde is useful for the preparation of various types of fully saturated hexaazamacrocyclic complexes containing N-CH 2 -N linkings [21]. Typical examples of primary amines side chain, the ''pendant arm'', that have been used so far include propylamine [22,23], ethanolamine [24,25], 1,4-phenylenediamine [26], hydrazine [27], 2-thiophenemethylamine [28], nicotinamide [5], 4-aminobutyric acid [29,30], ethylamine [31], (R)-(? )-1-(1-naphthyl)ethylamine [32], ethylenediamine [33], 1-(3-aminopropyl)-imidazole [34], benzylamine [1,35], and (R/S)-a-methylbenzylamine [36][37][38][39].…”

Synthesis, characterization, photophysical, thermal and electrical properties of composite of polyaniline with zinc bis(8-hydroxyquinolate): a potent composite for electronic and optoelectronic use

“…These complexes nd wide range of applications in drug industry, cosmetics, metal catalysts, metalloenzymes etc. 28 Macrocyclic ligands with p-conjugation can improve the optical properties of metal complex. Zinc(II) is a suitable metal for any metal complex to show luminescence due to its d 10 electronic conguration because the excitation of electrons takes place easily.…”
