Heterobimetallic NiZn complexes featuring metal centers in distinct coordination environments have been synthesized using diimine–dioxime ligands as binucleating scaffolds. A tetramethylfuran-containing ligand derivative enables a stable one-electron-reduced S 1⁄4 1/2 species to be accessed using Cp2Co as a chemical reductant. The resulting pseudo-square planar complex exhibits spectroscopic an...

The first probe for the fluorogenic determination of acetyl phosphate (AcP), (bpy)(2)Ru(1,10-phenanthroline-5,6-dione dioxime) (RuPDO), was prepared and its reaction with AcP was studied in detail. The emission of the weakly luminescent RuPDO is red shifted and strongly enhanced upon reaction with AcP in the presence of metal cations like Zn(2+) or Cu(2+). The reaction occurs within 60 min incu...

Heavy metal ions are harmful for entomopathogenic fungi. Derivatives of starch dialdehyde such as dihydrazone (DHZ), dithiosemicarbazone (DTSC), and dioxime (DOX) were used to form water-insoluble complexes with heavy metal ions. This phenomenon thus provided protection of entomopathogenic fungus Paecilomyces farinosus from the toxic effects of heavy metal ions. The fungus growth and the sporul...
