Structural Diversity of Ethinyl Estradiol Solvates

open access: yes, 2016
The (pseudo)polymorphism of ethinyl estradiol was investigated via extensive crystallization experiments. Four new crystal structures of ethinyl estradiol solvates that resulted from this study are presented.

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.

Praziquantel Fifty Years on: A Comprehensive Overview of Its Solid State

open access: yesPharmaceutics, 2023
This review discusses the entire progress made on the anthelmintic drug praziquantel, focusing on the solid state and, therefore, on anhydrous crystalline polymorphs, amorphous forms, and multicomponent systems (i.e., hydrates, solvates, and cocrystals).

Combined Use of Structure Analysis, Studies of Molecular Association in Solution, and Molecular Modelling to Understand the Different Propensities of Dihydroxybenzoic Acids to Form Solid Phases

open access: yesPharmaceutics, 2021
The arrangement of hydroxyl groups in the benzene ring has a significant effect on the propensity of dihydroxybenzoic acids (diOHBAs) to form different solid phases when crystallized from solution. All six diOHBAs were categorized into distinctive groups

Crystallographic Study of Solvates and Solvate Hydrates of an Antibacterial Furazidin [PDF]

open access: yes, 2022
In this study we present a detailed crystallographic analysis of multiple solvates of an antibacterial furazidin. Solvate formation of furazidin was investigated by crystallizing it from pure solvents and solvent-water mixtures.

Study on Fundamental Properties of Solvate Electrolytes and Their Application in Batteries

open access: yesElectrochemistry, 2022
Li salts and polar solvents form solvates, and certain solvates have low melting temperatures and remain in a liquid state at room temperature. Liquid-state solvates exhibit ionic conductivity and can be used as electrolytes in lithium batteries.

A Comparison Study of Roseolumiflavin Solvates: Structural and Energetic Perspective on Their Stability

open access: yesCrystals, 2023
Roseolumiflavin is a deep red microcrystalline derivative of isoalloxazine that exhibits a weak photophysical activity in the solid state. In aqueous as well as in acidic solution of formic or acetic acid, respectively, it tends to form solvates. Herein,
