Computational and Experimental Studies Into the Conformations of a Triptycene-Based Ditopic Ligand
(MDPI, 2015)
We present a combined computational and experimental study of the possible conformations adopted by a ditopic Schiff base ligand based on triptycene. We have performed DFT calculations on a Y-shaped Schiff base ligand ...
Synthesis and Characterization of a New Triptycene-Based Tripod
(MDPI, 2015)
Herein, we report an efficient and facile synthesis of a new triptycene based tripodal ligand containing both imine functionality and phenolic pendant arms. This tripodal unit is a potential building block for constructing ...
Different Bridging Preferences of Zinc and Palladium in Dimeric Complexes of a Ligand Based on 2-Tosylaminomethylaniline
(MDPI, 2015)
We report here the formation of dimeric palladium(II) and zinc(II) complexes of a ligand (H2L) derived from the condensation of 2 tosylaminomethylaniline and 2,3-dihydroxybenzaldehyde.The structures in solution of the ...
Total Hydrolysis of a New Imidazolidine Induced by ZnII
(MDPI, 2015)
2,2´-(2-(2-hydroxyphenyl)imidazolidin-1,3-diyl)diethanol(H3L) was obtained by condensation between 2-hydroxybenzaldehyde and N,N'-bis(2-hydroxyethyl)ethylenediamine. Its potential ability as NNOOO donor towards ZnII was ...
A heteronuclear ZnGd complex as a potential contrast agent for magnetic resonance imaging
(MDPI, 2016)
A new ligand H3L, with internal compartments for allocating 3d metal ions and external donors to bind 4f ions, was synthesized and completely characterized. Reaction of H3L with zinc(II) and gadolin ium(III) salts allows ...
H-Bonded Polymerisation of Alternate Δ and Λ Metallohelicates
(MDPI, 2015)
he neutral cadmium(II) complex Cd(HL)2 (H2L = 2-[(1H-imidazol-2-yl)methyleneamino]phenol) is chiral and it can be considered as a simple metallohelicate, with its corresponding Δ and Λ enantiomers. In the solid state, its ...
A simple route to dinuclear metal complexes of a sulfonamide ligand with a potential interest in the catalysis field
(MDPI, 2015)
We report here the straightforward synthesis of some d-block metal dimers of a Schiff base ligand obtained by condensation of 2‑tosylaminomethylaniline with 4-formyl-3-hydroxybenzoic acid (H2L). The easy bideprotonation ...
The crystal structure of a compartmental heptadentate ligand
(MDPI, 2009)
2-(2-hydroxyphenyl)-1,3-bis[4-(2-hydroxyphenyl)-3-azabut-3-enyl]-1,3-imidazolidine (H3L) was obtained with high purity by Schiff's condensation between 5-bromosalicyaldehyde and triethylenetetramine. Its recrystallisation ...
Imine-tetrahydroquinazoline tautomerism in a tosilated Schiff base
(MDPI, 2010)
Condensation of the selectively tosilated N-(2-aminobenzyl)-4-methylbenzenesulfonamide with 2-hydroxybenzaldehyde gives rise to (E)-N-(2-(2- hydroxybenzylideneamino)benzyl)-4-methylbenzenesulfonamide in the solid state, ...
Double imidazolidine condensation in a polynucleating Schiff base
(MDPI, 2010)
Condensation of pentaethylenehexamine and 3-bromo-5-chlorosalicylaldehyde yielded the bisimidazolidine Schiff base ligand 5,6\'-(1E,1\'E)-(2,2\'-(3,3\'-(ethane-1,2- diyl)bis(2-(3-bromo-5-chloro-2-hydroxyphenyl)imidazolid ...
