A neutron diffraction study of hydrogen bonding in isostructural potassium and ammonium lanthanoidates

An ESIPT Fluorophore Based on Zinc‐Induced Intramolecular Proton Transfer between Ligands in the Complex

“…It is well known that metal complexes provide the best combination of versatility and stability, and they could provide the desired physical and optical properties . Additionally, it should be pointed out that metal ions usually coordinate ligands such that the latter are in close proximity, paving the way for the formation of strong intramolecular hydrogen bonds between the coordinated ligands in the complexes . Meanwhile, structural deformation in the excited state can be inhibited by the rigid molecular structure formed upon metal coordination, which is beneficial for a high quantum yield .…”

Anion–Anion Interactions in the Crystal Packing of Functionalized Methanide Anions: An Experimental and Computational Study

“…The organic salts of the carbamoyldicyanomethanide anion have been broadly studied for their ability to form a variety of anionic hydrogen-bonded networks, with engineering of the hydrogen-bonding motifs present within the crystal structure made possible by the judicial selection of counter-cation . However, the supramolecular chemistry of the other organic methanide salts remains relatively unexamined, despite the fact their unique electronic structure may offer insights into supramolecular interactions between anions.…”

Conversion of amino-terephthalonitriles to multi-substituted single benzene fluorophores with utility in bioimaging

“…To find the reason for this deviation, we have looked into two other possibilities of the ground state geometries. (1) Intermolecular hydrogen bonding is a well-known feature of amides 19 and our studies have identified H-bonding of the CO and H–N moieties between two amide molecules of 13A in addition to the previously mentioned one (intramolecular H-bonding between –NH and –OEt). This dimer (Fig.…”
