Mo(III), Fe(III), Cd(II), Zn(II), Cu(II) complexes based on Tris[2-salicylaldeneimino)ethyl]amine (H3saltren) have been successfully synthesized. Newly prepared compounds have been characterized by 1H-NMR, 13C-NMR, IR and UV–VIS spectroscopy techniques. The spectral studies confirmed the ligand coordinates the metal ion to form complex via the oxygen and nitroge...

The syntheses of [FeL][BF(4)](2).H(2)O, [FeL][ClO(4)](2).H(2)O, [FeL][NO(3)](2).CH(3)NO(2) and [FeL][CF(3)SO(3)](2) (L = tris(4-{pyrazol-3-yl}-3-aza-3-butenyl)amine) are described. The isostructural BF(4)(-) and ClO(4)(-) salts are high-spin between 5-300 K, while the other two compounds are high-spin at room temperature but undergo gradual high-->low spin transitions upon cooling. For [FeL][NO...

Over the past decades the importance of metals in biology has been increasingly recognised. Approximately one third of the human proteome contains metal cations, either in the form of cofactors, with catalytic function, or as structural support elements. Moreover, a growing number of diseases have been identified that are characterised by metal imbalance in cells and tissues. Hence, the identif...
