Crystal structure of nicotinamide ethylene glycol hemisolvate [PDF]

open access: yesActa Crystallographica Section E: Crystallographic Communications
In the title solvate, C6H6N2O·0.5C2H6O2, the asymmetric unit consists of one nicotinamide molecule and half of an ethylene glycol molecule, which is completed by crystallographic inversion symmetry.

Kamlet–Taft Solvation Parameters of Solvate Ionic Liquids

open access: yesChemPhysChem, 2016
AbstractThe Kamlet–Taft solvent parameters of solvate ionic liquids (SILs) prepared from lithium salts with glyme and glycol ligands are determined. The dipolarity/polarisibilities (π*) are high, similar to those found in conventional ionic liquids. The H‐bond basicities (β) depend strongly on the anion.

Crystallization Selectivity of Ribavirin Solution and Amorphous Phase

open access: yesMolecules, 2023
Crystallization selectivity is an important principle in polymorph control. Ribavirin Form I, Form II, DMSO solvate, and amorphous ribavirin are prepared, and the short-range order similarities between these solid forms and ribavirin aqueous solution and

Formation of a solvate of manganese(III) acetylacetonate with chloroform

open access: yesКонденсированные среды и межфазные границы, 2022
Metal acetylacetonates are coordination compounds consisting of the acetylacetonate anion (CH3COCHCOCH3, indicated as acac) and metal ions. Typically, both oxygen atoms of the anion bind with the metal and form a six-membered chelate ring.
