Two different products from the reaction between 2-formyl­phenyl­boronic acid and benzhydrazide: benzoyl hydrazone versus dimer

After the reaction between 2-formyl­phenyl­boronic acid and benzhydrazide, one of the two products was isolated. The reaction outcome is modulated by solvent choice; performing the reaction in water gives a benzoyl hydrazone and conducting the reaction in ethanol leads to the isolation of a dimer product. These findings are supported using a combination of X-ray crystallography and NMR and high-resolution mass spectrometry (HRMS) data.

Synthesis, structure and characterization of a new glycolate: sodium glycolate–glycolic acid (1/1)

Sodium glycolate–glycolic acid (SGGA), Na(C₂H₃O₃)(C₂H₄O₃), was synthesized to investigate the role of Na⁺ in the `A′ site of A(C₂H₃O₃)(C₂H₄O₃) glycolates. SGGA crystallizes in the chiral ortho­rhom­bic space group P2₁2₁2₁, despite lacking chiral C atoms. The bonding behaviour of glycolic acid and the structural function of Na⁺ have been clarified, offering insights for the discovery of new minerals.

Comprehensive structural analysis of bromine-substituted ferro­cenyl chalcones

Three novel crystal structures for bromine-substituted ferro­cen­yl chalcones are reported, as well as an in-depth structural study that includes five structures within the series of com­pounds. The effect of bromine substitution on the aromatic ring and enone connectivity of the ferro­cen­yl chalcones was evaluated over crystal structure and supra­molecular features. A Hirshfeld surface analysis is also developed.

Crystal structures, cytotoxicity studies and inter­actions with DNA of novel in situ-formed com­plexes containing N-scorpionate ligands and nitrate ions

Three com­plexes were synthesized in an efficient one-pot synthesis. They show potent anti­proliferative activity combined with their great selectivity towards cancer cells.

Cocrystals of cyan­uric acid with di(pyridin-4-yl)sulfane and 1,2-di(pyridin-4-yl)disulfane obtained from 4-mer­cap­topyridine under controlled illumination conditions

Crystallization of 4-mer­cap­to­pyridine with cyan­uric acid under controlled illumination conditions yields three co­crys­tals and reveals how UV irradiation alters solution speciation and the resulting solid forms.
