A merged experimental and theoretical conformational study on alkaline-earth complexes with lariat ethers derived from 4,13-diaza-18-crown-6
(Elsevier, 2011-02-05)[Abstract] Herein, we report the synthesis and structural characterization of alkaline-earth complexes with the bibracchial lariat ethers N,N′-bis(2-aminobenzyl)-4,13-diaza-18-crown-6 (L2) and N,N′-bis(benzimidazol-2ylme ... -
Binuclear Co(II), Ni(II), Cu(II) and Zn(II) complexes with Schiff-bases derived from crown ether platforms: rare examples of ether oxygen atoms bridging metal centers
(Elsevier, 2010-05-26)[Abstract] Bibracchial lariat ethers L3 and L4, derived from the condensation of N,N′-bis(2-aminobenzyl)-1,10-diaza-15-crown-5 or N,N′-bis(2-aminobenzyl)-4,13-diaza-18-crown-6 with salicylaldehyde, form binuclear complexes ... -
Cinderella Elements: Strategies to Increase the Stability of Group 1 Complexes by Tailoring Crown Macrocycles
(Elsevier, 2014-06-01)[Abstract] The synthesis and structural characterization of six sodium complexes with bibracchial lariatethers containing aniline or benzimidazole side arms, and derived from 1,7 diaza-12-crown-4, 1,10-diaza-15-crown-5 or ... -
Designing binuclear transition metal complexes: a new example of the versatility of N,N′-bis(2-aminobenzyl)-4,13-diaza-18-crown-6
(Royal Society of Chemistry, 2005-04-27)[Abstract] N,N′-Bis(2-aminobenzyl)-4,13-diaza-18-crown-6 (L) is a versatile receptor able to adapt to the coordinative preferences of different metal cation guests. With first-row transition metal ions, L tends to form ... -
In-depth study of a novel class of ditopic gadolinium(III)-based MRI probes sensitive to zwitterionic neurotransmitters
(Frontiers, 2019-07-24)[Abstract] The efficacy of Gd-based low-molecular weight ditopic MRI probes on binding zwitterionic neurotransmitters (ZNTs) relies on their structural compatibility. ZNTs are challenging biomarkers for monitoring chemical ... -
Solid state and solution structures of alkaline-earth complexes with lariat ethers containing aniline and benzimidazole pendants
(Elsevier, 2012-01-04)[Abstract] Herein we report the synthesis and structural characterization of Mg(II), Ca(II), Sr(II) and Ba(II) complexes with bibracchial lariat ethers derived from 1,7-diaza-15-crown-5 and 1,7-diaza-12-crown-4 containing ... -
The effect of ring size variation on the structure and stability of lanthanide(III) complexes with crown ethers containing picolinate pendants
(Royal Society of Chemistry, 2011-01-14)[Abstract] The coordination properties of the macrocyclic receptor N,N′-bis[(6-carboxy-2-pyridyl)methylene]-1,10-diaza-15-crown-5 (H2bp15c5) towards the lanthanide ions are reported. Thermodynamic stability constants were ...
