Solvent influence on the crystal structures of new cadmium tri-tert-but­oxy­silane­thiol­ate com­plexes with 1,4-bis­(3-amino­prop­yl)pi­per­azine: luminescence and anti­fungal activity

Two cadmium tri-tert-but­oxy­silane­thiol­ates with 1,4-bis­(3-amino­prop­yl)pi­per­a­zine were obtained from identical molar ratios of reagents in different solvents. The structures of the com­plexes have a direct impact on their spectral properties, as well as their anti­fungal properties.

Low-dimensional com­pounds containing bioactive ligands. XXII. First crystal structure, cytotoxic activity and DNA and HSA binding of a zirconium(IV) com­plex with 8-hy­droxy­quinoline-2-carb­oxy­lic acid

A new zirconium(IV) com­plex, [Zr(QCa)₂(H₂O)₂]·2DMF, with 8-hy­droxy­quinoline-2-carb­oxy­lic acid (HQCaH) was prepared and characterized. The Zr^IV atom in this mononuclear com­plex is octa­coordinated by two QCa²⁻ ligands and two aqua ligands. The com­plex and the HQCaH ligand showed low anti­cancer activity with IC₅₀ > 200 µM. On the other hand, the com­plex inter­calates in CT DNA and also inter­acts with HSA.

The synthesis and crystal structure of (E)-2-{[(4-meth­oxy­naph­tha­len-1-yl)methyl­idene]amino}-4-methyl­phenol: Hirshfeld surface analysis, DFT calculations and anti­corrosion studies

The title Schiff base was synthesized by the reaction of 2-amino-4-methyl­phenol with 4-meth­oxy­naph­tha­lene-1-carbaldehyde in a 1:1 ratio. The com­pound exhibits significant anti­corrosion properties for iron and copper.
