Journal ArticleDOI
Carboxy and Phosphate Esters Cleavage with Mono- and Dinuclear Zinc(II) Macrocyclic Complexes in Aqueous Solution. Crystal Structure of [Zn2L1(μ-PP)2(MeOH)2](ClO4)2 (L1 = [30]aneN6O4, PP- = Diphenyl Phosphate)

TL;DR: The hydrolysis rate of BNP is increased almost 10-fold by the dinuclear [Zn(2)L1(OH)(2)](2+) complex with respect to the mononuclear L2-Zn-OH(+) one, indicating a cooperative role of the two metals in the hydrolytic mechanism.
Journal ArticleDOI
Thermodynamic and structural properties of Gd(III) complexes with polyamino-polycarboxylic ligands: basic compounds for the development of MRI contrast agents
Antonio Bianchi,Luisella Calabi,Federica Corana,Stefano Fontana,Pietro Losi,Alessandro Maiocchi,Lino Paleari,Barbara Valtancoli +7 more
TL;DR: In this paper, the main purpose of the review is to collect equilibrium data in aqueous solution and structural properties in the solid state for significant examples of Gd(III) complexes with both acyclic and macrocyclic polyamino polycarboxylic ligands.
Journal ArticleDOI
Thermodynamics of phosphate and pyrophosphate anions binding by polyammonium receptors
Carla Bazzicalupi,Andrea Bencini,Antonio Bianchi,Mirco Cecchi,Beatriz Escuder,Vieri Fusi,Enrique García-España,Claudia Giorgi,Santiago V. Luis,Gianluca Maccagni,Victor Marcelino,Piero Paoletti,Barbara Valtancoli +12 more
TL;DR: Very stable 1:1 receptor-to-anion complexes are formed as discussed by the authors, and the stability trends of such complexes are not strictly determined by electrostatic forces, hydrogen bond interactions being of considerable importance in the complex formation, the thermodynamic data being consistent with different hydrogen bonding modes.
Journal ArticleDOI
Carboxy and Diphosphate Ester Hydrolysis by a Dizinc Complex with a New Alcohol-Pendant Macrocycle
Carla Bazzicalupi,Andrea Bencini,Emanuela Berni,Antonio Bianchi,Valentina Fedi,Vieri Fusi,Claudia Giorgi,Piero Paoletti,Barbara Valtancoli +8 more
TL;DR: In this paper, the authors reported the synthesis of the new alcohol-pendant macrocycle 4-(2-hydroxyethyl)-1,4,7,16,19,22-hexaaza-10,13,25,28-tetraoxacyclotriacontane (L2) is reported.
Journal ArticleDOI
CO2 Fixation by Novel Copper(II) and Zinc(II) Macrocyclic Complexes. A Solution and Solid State Study
Carla Bazzicalupi,Alessandro Bencini,Andrea Bencini,Antonio Bianchi,Federica Corana,Vieri Fusi,Claudia Giorgi,Paola Paoli,Piero Paoletti,Barbara Valtancoli,Claudia Zanchini +10 more
TL;DR: In order to test the nucleophilic ability of the Zn(II) complexes, the kinetics of the promoted hydrolysis of p-nitrophenyl acetate has been studied and the spectromagnetic behavior of 4 has be studied.
