research papersresearch papersMulticomponent crystals of nitroimidazole drugs with trithiocyanuric acid: two competing drug–coformer supramolecular motifs
Trithiocyanuric acid forms either R22(8) dimers or linear chain motifs in nitroimidazole cocrystals, giving rise to two competing drug–coformer supramolecular binding schemes.
research papersWhen the crucible contributes: serendipitous formation, flux reactivity, and crystal and electronic structures of two aluminium-bearing mixed-metal oxides
Alumina crucibles act as unintended aluminium sources in Pb-flux syntheses, yielding two heavily disordered metal oxides, with Pb3GeAl10O20- and BaZnGeO4-related structures.
research papersUranyl derivatives: discovering features by comparing related crystal structures
A brief overview of the existing data on related UO22+-containing crystal structures uncovered some peculiarities about three new derivatives. The first crystal structure with simultaneously present H3O+ and Be2+ cations was solved. The rigidity of topology to the change of the nature of the fragments and ways to control the atom environment via the ratio of the reagents are discussed.
research papersTuning helical chirality and physical properties in chiral lactate-based coordination polymers by varying metal centres and auxiliary ligands
By altering the metal centre and auxiliary ligand, two chiral lactate-based coordination polymers exhibit distinct helical chirality expressions and properties.
research papersSynthesis, structural characterization, and electronic structure of monoclinic α-[SeCl3][MoOCl4]
Moisture-sensitive trichloridoselenium tetrachloridooxidomolybdate, α-[SeCl3][MoOCl4], was synthesized from MoOCl4 and Se2Cl2, and structurally characterized by single-crystal X-ray diffraction, revealing a layered ionic solid comprising [SeCl3]+ cations and dimeric [Mo2O2Cl8]2− anions linked through secondary Se⋯Cl interactions, with electronic structure analysis indicating semiconducting behavior.
research papersWater-bridged tetrameric supramolecular synthons in a novel tetrasubstituted imidazole–phenylalanine derivative synthesized via a Debus–Radziszewski reaction
A new imidazole derivative of phenylalanine was synthesized, the crystals displaying dimeric and/or tetrameric structures with unusual water double bridges.
research papersYK-4-250, a synthetic telmisartan–tempol conjugate: crystal structure of a stabilized free radical containing an angiotensin AT1 receptor inhibitor
The first crystal structure of the telmisartan–tempol conjugate YK-4-250 is reported, revealing the intramolecular C–H⋯π interactions that stabilize the nitroxide radical while preserving the angiotensin AT1 receptor antagonist pharmacophore.
research papersPeculiarity of atomic displacements in garnets discovered through a single-crystal X-ray diffraction study of the Na-bearing vanadate garnet series
Garnets where the mean-square displacements of the tetrahedral cations are largest in the direction of adjacent dodecahedral cations were discovered through structure refinements of the Na-bearing vanadate garnet series. This peculiar atomic displacement behaviour occurs when the dodecahedral sites are occupied by different cation species with different valences and largely different sizes.
