highly crystalline bi3+-doped cadmium oxide (cdo) sub-micron structures were synthesized by calcination the obtained precursor from a sol-gel reaction. the reaction was carried out with cadmium nitrate (cd(no3)2.4h2o), bismuth nitrate (bi(no3)3.5h2o) and ethylene glycol (c2h6o2) reactants without any additives at 80°c for 2h. resulting gel was calcined at 900 °c with increasing temperature rate...

Reactions of cadmium(II) thioand selenocyanate with 4-acetylpyridine in different molar ratios and in different solvents always lead to the formation of compounds of composition Cd(NCS)2(4acetylpyridine)2 (Cd1-I) and Cd(NCSe)2(4-acetylpyridine)2 (Cd2). Both compounds are isotypic and crystallize in the monoclinic space group C2/c. In their crystal structures the Cd cations are coordinated by tw...

The X-ray structural chemistry of zinc and cadmium 1,1-dithiolates (for example, xanthate, dithiophosphate and dithiocarbamate) with potentially bridging bipyridyl-type ligands (for example, 4,4′-bipyridine) is reviewed. For zinc, the xanthates and dithiophosphates uniformly form one-dimensional coordination polymers, whereas the zinc dithiocarbamates are always zero-dimensional, reflecting the...

background: presence of heavy metals in leachate due to the biological accumulation characteristics of these materials endangered the living creatures' health especially human. purpose of this study is to study and investigate the possibility of two metals' absorption i.e, lead and cadmium from leachate by natural zeolite clinopteliolit and increase of the ability to absorb the zeolite by modif...

Cadmium(II) complexes with thiolate ligands have received considerable attention because of their intriguing structural features and relevance to metalloproteins. In this study, a new cadmium(II)–rhodium(III) trinuclear complex, [Cd{Rh(apt)3}2]Br2·4H2O (1, apt = 3-aminopropanethiolate), was synthesized by the reaction fac-[Rh(apt)3] cadmium bromide. Compound 1 characterized using elemental anal...

mono and bis hexamethylenetetramine iron(iii) chloride, fe(n c ,h ) ci (i) and fe(n c ,h ) cl (ii) were synthesized by the reaction of iron(iii) chloride and hexamethylenetetramine (hmta) in chloroform. chemical analysis and spectral results show the coordination of hmta to the iron(iii). electronic transition spectra of compound i and i1 were also studied in coordinating and noncoordinating so...

Development of components that can form large molecular aggregates through non–covalent interactions, in nano size structures, has been an active area of research. In current study, a nano-sized Pb(II) coordination polymer, {[Pb(pydc)(pydc.H2)(H2O)2]2}n (1), where [pydc.H2= 2,6-pyridinedicarboxylic acid), wer...
