Two isotypical disodium salts of the anti­hypertensive agent valsartan

The crystal structures of two isotypical disodium salts of the antihypertensive agent valsartan were characterized using powder and single-crystal X-ray diffraction.

Charge-enhanced pyri­dyl tri­fluoro­borate organocatalysts: crystal structures and reactivity

An examination of the relationship between the solid-state features of the crystal structures of eleven 3- and 4-pyridyl tri­fluoro­borate organocatalysts and their solution-state reactivity is reported.

Methyl-group effect on the photoluminescence property of a spiro­[fluorene-9,9'-xanthene] derivative: a structural and spectroscopic study

The structural and photoluminescent properties of 1′,3′,6′,8′-tetra­methyl­spiro­[fluorene-9,9′-xanthene] were explored, emphasizing the importance of methyl groups in enhancing fluorescence. Single-crystal X-ray diffraction revealed a unique 90° crossover between the fluorene and xanthene segments.

An indole–pyridine Schiff base and its cadmium(II) com­plex: crystallographic and biological insights

A novel indole–pyridine Schiff base (3-D) and its cadmium(II) com­plex (3-D-Cd) were synthesized, fully characterized and evaluated for cytotoxicity. While 3-D exhibited minimal toxicity toward both cancerous and normal cells, 3-D-Cd showed selective cytotoxicity, displaying reduced toxicity toward normal cells. Compared to CdCl₂, 3-D-Cd was significantly less toxic to most cell lines – excluding HeLa – suggesting that 3-D may attenuate Cd^II-induced toxicity.

A new combination to form a solid solution: a solid solution consisting of a stabilized phenoxyl radical and its meth­oxy analogue

The 2,4,6-tris­(4-tert-butyl­phen­yl)phenoxyl radical formed two solid solutions with its meth­oxy analogue. According to single-crystal X-ray analysis, the crystal structure of each solid solution is thought to be dominated by the characters of the main com­ponents.
