Three polymorphic structures of mefenamic acid, which is a very popular drug, have been studied using quantum chemical methods. It has been shown that the centrosymmetric dimer formed due to two O-H···O hydrogen bonds is a complex building unit in

Being well studied, I and II polymorphic structures of aspirin are very suitable for testing a new method to study mechanical properties using quantum chemical calculations. The proposed method con...

Polymorphism is the phenomenon of the existence of different arrangements of molecules in the crystal phase. Molecules can differ in conformations (conformational polymorphism) and / or in intermolecular interactions between them in the crystal (orie

In this paper we present the results of polymethylmethacrylate (PMMA) impregnation with carbamazepine (CBZ) in a supercritical carbon dioxide (scCO2) medium at two different temperatures (75 °C and 105 °C) at a constant CO2 density. The obtained im

In this work, we studied the high-temperature polymorphic conversion of carbamazepine (CBZ) in a high-density supercritical CO2 (scCO2) medium in the temperature range of 110–200°C. In order to understand the mechanism of transformation we perform

Two new dibenzocrown ethers and molecular clips were synthesized. The influence of substituents on the terminal aromatic fragments of the clips on the paraquat-complex stability constants were studied. The “pseudocryptand” type complex of fluorin
