Understanding the nature and the strength of metal-ligand interactions in d- and f-block metal complexes has always been a central issue for both synthetic and theoretical chemists. These interactions are usually described according to the well accepted Dewar-Chatt-Duncanson model, and thus over the years numerous research groups directed their efforts to shed light on the role of σ- and π-cont...

BACKGROUND Cyanide is one of the most toxic chemicals produced by anthropogenic activities like mining and jewelry industries, which generate wastewater residues with high concentrations of this compound. Pseudomonas pseudoalcaligenes CECT5344 is a model microorganism to be used in detoxification of industrial wastewaters containing not only free cyanide (CN(-)) but also cyano-derivatives, such...

Water resource scarcity, population growth, pollution of surface and groundwater by discharging toxic wastewater and subsequent diseases may raise the necessity of reusing and treatment of wastewater. Cyanide is one of the toxic materials which can be found in some industrial wastewaters. Strict laws set by international bodies have forced industries to work on developing efficient cyanide remo...

Due to the present water shortage and environmental problems associated with industrial effluent, investigation of novel treatment technologies is an essential approach. Being a highly toxic chemical of asphyxiating characteristics, cyanide is seen as a major environmental pollutant in a wide range of industrial effluents. The present study aimed to address the adsorption and photocatalytic deg...

A highly purified preparation of cytochrome c peroxidase was prepared by reconstituting the enzyme from the apoprotein and protohemin. Paramagnetic susceptibilities of the enzyme and of its complexes with cyanide, azide, cyanate, and fluoride were measured at temperatures from 77” K to 273” K. The susceptibilities of the cyanide and fluoride complexes obeyed Curie’s law over the entire temperat...

Chiral C(2)-symmetric electroactive bis(oxazolines) containing an EDT-TTF (ethylenedithio-tetrathiafulvalene) backbone, as promising multifunctional ligands and precursors for chiral molecular materials, were synthesized and structurally characterized, together with octahedral molybdenum and tungsten carbonyl complexes.

Horseradish peroxidase forms spectroscopically distinct, reversible complexes with hydroxamic acids (R-CONHOH), hydrazides (RCO-NHNH2), amides (RCONH2), and oc-hydroxyketones (RCO--CHsOH). Binding of these compounds to the enzyme depends on the polar and steric character of R and the hydrogen bonding capacity of-COX-Y (X-Y = NH-OH, NH-NH,, NH-H, CH,OH). Hydroxamate anions and hydrazide cations ...
