(IF 4.0) Pub Date : 2024-05-13 Corinne Vanucci-Bacqué, Mariusz Wolff, Beatrice Delavaux-Nicot, abanoub Mosaad Abdallah, Sonia Mallet-Ladeira, Charles-Louis Serpentini, Florence Bedos-Belval, Kar Wai Fong, Xiao Ying Ng, May Lee Low, Eric Benoist, Suzanne Fery-Forgues
The tricarbonylrhenium complexes that incorporate a mesoionic carbene ligand represent an emerging and promising class of molecules, the solid-state optical properties of which have rarely been investigated. The aim of this comprehensive study is to compare three of these complexes with their 1,2,3-triazole-based analogs. The Hirshfeld surface analysis of the crystallographic data revealed that the

Step-Wise Changes in the Excited State Lifetime of [Eu(D2O)9]3+ and [Eu(DOTA)(D2O)]- as a Function of the Number of Inner-Sphere O-H Oscillators Dalton Trans. (IF 4.0) Pub Date : 2024-05-13 Nicolaj Kofod, Thomas Just Sørensen
Lanthanide luminescence is dominated by quenching from high-energy oscillators in the chemical environment. The rate of non-radiative energy transfer to a single H2O molecule coordinated to a Eu3+ ion exceeds the usual rates of emission by an order of magnitude. We know these rates, but the details of these energy transfer processes are yet to be established. In this work, we study the quenching rates

Zinc(II)-complexes with the general formula [Zn(L)2] containing 8-hydroxyquinoline Schiff bases functionalized with 1-(3-aminopropyl)imidazole or 1-(3-aminopropyl)-2- methyl-1H-imidazole on 2-position and their respective ligands (HL1 or HL2) were synthesized and characterized by NMR, UV-Vis, FTIR and CD spectroscopies as well as ESI-MS spectrometry. Single crystals of HL2 and [Zn(L1)2]n were analysed

An Elastic Single Crystal Composed of One-dimensional Chiral Coordination Polymers Dalton Trans. (IF 4.0) Pub Date : 2024-05-13 Yan Zhang, Yu-Xia Li, Kaige Gao, Jia-Hui Zhang, Jie-Sheng Hu, Jun Tao, Zi-Shuo Yao
A single crystal composed of one-dimensional coordinated polymers, [CdCl2(1-Methyl-2-pyridone)]n, has been synthesized and characterized. This compound exhibits outstanding elastic bending due to the molecular spring nature of the CdCl2 coordination framework and weak intermolecular interactions between the coordination chains. Owing to the helical arrangement of organic ligands surrounding the coordination
