Two New Supramolecular Architectures of Singly Phenoxo‐Bridged Copper(II) and Doubly Phenoxo‐Bridged Manganese(II) Complexes Derived from an Unusual ONOO Donor Hydrazone Ligand: Syntheses, Structural Variations, Cryomagnetic, DFT, and EPR Studies
A library of acylhydrazone iron chelators was synthesized and tested for its ability to inhibit the growth of a chloroquine-resistant strain of Plasmodium falciparum. Some of these new compounds are significantly more active than desferrioxamine DFO, the iron chelator in widespread clinical use and also than the most effective chelators. (c) 2005 Elsevier Ltd.

Two new hydrogen-bonded supramolecular dioxo-molybdenum(VI) complexes based on acetyl-hydrazone ligands: Synthesis, crystal structure and DFT studies
complexes [MoO2L1(H2O)] (1) and [MoO2L2(H2O)] (2) have been synthesized using two different tridentate hydrazone Schiff base ligands, L1H2 [(E)-N-(2-hydroxybenzylidene)acetohydrazide] and L2H2 [(E)-N-(2-hydroxy-3-methoxybenzylidene)acetohydrazide], respectively. The ligands and their corresponding Mo complexes are thoroughly characterized by different physicochemical techniques. Molecular structures
