The asymmetric unit of the title compound, [Cd(NCS)2(CH3CN)] n , consists of one Cd(II) cation, two thio-cyanate anions and one aceto-nitrile ligand, all in general positions. The Cd(II) cation is coordinated by three N atoms of two thio-cyanate anions and one aceto-nitrile ligand, as well as three S atoms of symmetry-related thio-cyanate anions within a slightly distorted octa-hedral coordinat...

In the title compound, [Cd(2)Cl(6)(C(4)H(10)NO)(2)](n), the coordination geometry of each Cd(II) ion is distorted octa-hedral, but with quite different coordination environments. One Cd(II) atom is coordinated by four Cl atoms and two O atoms from two morpholinium ligands, while the other is coordinated by six Cl atoms. Adjacent Cd(II) atoms are inter-connected alternately by paired chloride br...

Novel copper(II) coordination compounds with chiral macrocyclic imine ligands derived from R-/S-camphor were asymmetrically synthesized and characterized with the aid of chiroptical spectroscopies. Crystal structures of both enantiomers were determined by single crystal X-ray diffraction analysis. Circular dichroism (CD) spectra were analyzed using a simplified exciton model as well as quantum ...

In the title compound, [Cd(NCS)(2)(C(11)H(17)N(3))](n), the Cd(II) atom is octa-hedrally coordinated by the N,N',N''-tridentate Schiff base ligand and one terminal thio-cyanate N atom. Two trans-N:S-bridging thio-cyanates complete the N(5)S donor set around the Cd atom. In the crystal, adjacent Cd(II) ions are linked by the thio-cyanate N:S-bridges into polymeric chains along the c axis.

Batch adsorption studies were undertaken with the abundantly available waste biosorbent Tectona grandis L.f. leaf powder for removal of cadmium(II) from aqueous solutions. The adsorption experiments were performed under various conditions such as time, temperature, different initial Cd(II) concentrations, pH, adsorbent dosage, and adsorbent particle size. The data showed that in 30 minutes, 1 g...

Cd(II) and Pb(II) ions removal using adsorbents prepared from sub-bituminous coal, lignite, and a blend of coal and Irvingia gabonensis seed shells was investigated. Fourier transform infrared, scanning electron microscope and X-ray fluorescence analyses implicated hydroxyl, carbonyl, Al2O3, and SiO2 as being responsible for attaching the metal ions on the porous adsorbents. The optimum adsorpt...

Expression of the Tn21 mercury resistance (mer) operon is controlled by a metal-sensing repressor-activator, MerR. When present, MerR always binds to the same position on the DNA (the operator merO), repressing transcription of the structural genes merTPCAD in the absence of Hg(II) and inducing their transcription in the presence of Hg(II). Although it has two potential binding sites, the purif...

In the title two-dimensional coordination polymer, [Cd(NCS)(2)(C(6)H(5)N(5))(2)](n), the Cd(II) ion (site symmetry ) is coordinated by two N atoms from two 2-(1H-1,2,3-triazol-1-yl)pyrazine ligands and two N and two S atoms from four thio-cyanate anions. The N-Cd bond lengths range from 2.323 (2) to 2.3655 (19) Å and the S-Cd bond length is 2.7117 (7) Å. The associated cisoid angles vary from 8...

Polypores (woody pore fungi) biomass has been used as an biosorbent for the removal of Pb(II) and Cd(II) from aqueous solution under batch equilibrium experimental conditions. The resulting biosorbent is characterized by SEM and FTIR techniques. The effect of experimental parameters, such as solution pH, biomass dosage, contact time, initial metal ion concentration and temperature of Pb(II) and...
