research papersConcerning the structures of Lewis base adducts of titanium(IV) hexafluoroisopropoxide
The reaction of titanium(IV) chloride with sodium hexafluoroisopropoxide, carried out in hexafluoroisopropanol, produces titanium(IV) hexafluoroisopropoxide, which is a liquid at room temperature. Recrystallization from coordinating solvents, such as acetonitrile or tetrahydrofuran, results in the formation of bis-solvate complexes. These compounds are of interest as possible Ziegler–Natta polymerization catalysts.
topical reviewresearch papersComparison of the crystal structures of the JAK1/2 inhibitor ruxolitinib and its hydrate and phosphate
The crystal structures of ruxolitinib and its dihydrate and phosphate are described in detail and compared through the analysis of both Hirshfeld surfaces and fingerprint plots.
research papersCrystal structure and characterization of monascin from the extracts of Monascus purpureus-fermented rice
The compound monascin was extracted from Monascus purpureus-fermented rice and a novel solid form has been successfully crystallized and characterized using single-crystal X-ray diffraction.
feature articlesresearch papersThe pattern of bifurcated hydrogen bonds in thiourea cocrystals with diazine derivatives: experimental and quantum theoretical studies
The structures of two cocrystals were determined, i.e. thiourea with pyrazine N-oxide and phenazine. In the crystal structures, both molecular components are linked by N—H⋯N hydrogen bonds. Moreover, interactions of the N—H⋯S type are observed between thiourea molecules creating synthons. Furthermore, bifurcated hydrogen bonds between the thiourea molecule and azine derivatives play a significant role in both structures. This emerging motif was thoroughly examined using quantum chemistry methods.
