Pyridinium Salts of Dehydrated Lanthanide Polychlorides
Molecules, 2022 The reaction of lanthanide (Ln) chloride hydrates ([Ln(H2O)n(Cl)3]) with pyridine (py) yielded a set of dehydrated pyridinium (py-H) Ln-polychloride salts. These species were crystallographically characterized as [[py-H-py][py-H]2[LnCl6]] (Ln-6; Ln = La,

Catalytic Photochemical Enantioselective α-Alkylation with Pyridinium Salts [PDF]
, 2022 We have developed a chiral amine catalyzed enantioselective α-alkylation of aldehydes with amino acid derived pyridinium salts as alkylating reagents. The reaction proceeds in the presence of visible light (390 nm) and in the absence of a photocatalyst ...

Pyridinium Cations Act as Charge Reservoirs in Expanded Halide Perovskite Analogs at High Pressure. [PDF]
Angew Chem Int Ed EnglRedox‐innocent pyridinium derivatives can act as charge reservoirs in expanded tin‐iodide perovskite analogs. Material compression reduces the energy gap between the pyridinium π* acceptor orbital and the valence‐band maximum, facilitating electron transfer from the framework to the molecules and thereby significantly increasing electronic conductivity

Tetraaqua[3-oxo-1,3-bis(pyridinium-2-yl)propan-1-olato]nickel(II) tribromide dihydrate
Acta Crystallographica Section E: Crystallographic Communications, 2020 The crystal structure of the title compound, [Ni(C13H11N2O2)(H2O)4]Br3·2H2O, contains an octahedral NiII atom coordinated to the enol form of 1,3-dipyridylpropane-1,3-dione (dppo) and four water molecules. Both pyridyl rings on the ligand are protonated,

4-{(1E,3E)-4-[4-(Dimethylamino)phenyl]buta-1,3-dien-1-yl}-1-methylpyridin-1-ium iodide
IUCrData, 2016 The title molecular salt, C18H21N2+·I−, consists of a pyridinium cation and an I− anion. The cation exists in an E,E conformation with respect to the two C=C double bonds, and is roughly planar with the pyridinium ring being inclined to the benzene ring ...
