In the title mononuclear cadmium complex, [Cd(C(10)H(5)O(4))(2)(H(2)O)(2)], the Cd(II) atom, located on a crystallographic inversion center, exhibits a slightly distorted octa-hedral geometry and is six-coordinated by two O atoms from water mol-ecules in the axial positions and four O atoms from two deprotonated coumarin-3-carb-oxy-lic acid ligands in the equatorial plane. Angles around the Cd(...

the expensive nature of metal ions detoxification from wastewater have restricted the use of conventional treatment technologies. cheap, alternative measures have been adopted to eliminate metal contamination, and adsorptions using agricultural adsorbents seem to be the way forward. the use of agricultural adsorbents for cadmium (ii), copper (ii) and lead (ii) ion removal has gained more intere...

Two new coordination polymers, namely, poly[[μ3-3-(1H-benzimidazol-2-yl)propionato]zinc(II)], [Zn(C10H8N2O2)] n , (1), and poly[bis-[μ2-3-(1H-benzimid-azol-2-yl)propionato]cadmium(II)], [Cd(C10H8N2O2)2] n , (2) have been synthesized from 3-(1H-benzoimidazol-2-yl)propanoic acid ligands through a mixed-ligand synthetic strategy under a solvothermal environment, and studied by single-crystal X-ray...

Cadmium (Cd) brings a devastating health hazard to human being as a serious consequence of agricultural and environmental contamination. We demonstrated the protective effect of silicon (Si) on cadmium (Cd)-stressed rapeseed (Brassica napus L. cv. BINA Sharisha 3) plants through regulation of antioxidant defense and glyoxalase systems. Twelve-day-old seedlings were exposed to Cd stress (0.5 and...

Introduction Industrial effluents of metallurgical alloying, ceramics, electroplating, photography, pigment works, textile, printing, chemical industries, Cd/Ni batteries and lead mine drainage containing toxic metal such as cadmium (Wesley Eckenfelder Jr, 2000; Cheremisinoff, 1995). Higher concentration of cadmium causes gastrointestinal discomforts, kidney damage, nausea, vomiting, and diarrh...

The biosorption characteristics of Cd (II) ions using the living biomass of the marine diatom Phaeodactylum tricornutum were investigated. This microalga is a highly tolerant species to cadmium toxicity; for this reason, it is interesting to know its potential for use in the removal of this metal. The use of living biomass offers better possibilities than that of dead biomass since cadmium can ...

a novel pyridine-2,6-dicarboxylic acid mixed ligands complex of formula [co(no3)2].6h2o has been obtained by the reaction of pyridine-2,6-dicarboxylic acid with cobalt nitrate and 1,10-phenanthroline on heating in water. the structures of [co(pydc)(phen)(h2o)](pydch2).4h2o receptors, and their complexes were optimized using dft method at the b3lyp/3-21g** level. the highest occupied molecular o...

in this paper, nickel oxide (nio) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(ii) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(ii) chloride, [nil]cl2, in an electrical furnace at optimal temperature, 450 ºc for 3.5 h. the nickel(ii) complex is obtained via solid state synthesis using nickel(ii) chloride and tetradentate o4 acyclic ligan...
