In the title compound, [Ba(C(14)H(20)O(5))(2)][Co(NCS)(4)], the Ba(II) and Co(II) ions are situated on twofold rotational axes, so asymmetric unit contains half each of the complex cations and anions. The Co(II) ion is coordinated by four N atoms [Co-N 1.83 (2), 1.95 (3) Å] in a distorted tetra-hedral geometry. The Ba(II) ion is coordinated by ten O atoms [Ba-O 2.766 (19)-2.859 (19) Å] from two...

Purification of extra-cellular cellulolytic enzymes from C e l l u l o mssp. strain 0, isolated from forest soil in the north of Iran , was studied by using gel filtration and ion-exchange chromatography. Two endo-glucanases (Endo-I & Endo-II) and one exo-glucanase (Exo-I) were purified to hornogenity . The purified enzymes had molecular weights of about 39.000,70.000 and 90.000 daltons for ...

In the title compound, [Co(C(14)H(10)Br(2)NO)(2)], the Co(II) ion is coordinated by an O and an N atom from two equivalent 2-[(E)-benzyl-imino-meth-yl]-4,6-dibromo-phenolate ligands, displaying a distorted tetra-hedral geometry. The Co(II) ion occupies a special position on a twofold rotation axis and thus the mol-ecular symmetry of the complex is C(2). The two phenolate rings are perpendicular...

in present study, molecular dynamics simulation of cadmium (ii), lead (ii) and copper (ii) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. the results showed that, most of the particles had the highest affinity of ion exchanging with lead (ii) and the lowest affinity with copper (ii). the calculated mean ion-exchange ratios showed t...

Cadmium is one of the many toxic elements for humans even at low concentrations, and it could exist in environment a long time. The ion imprinting technique has gained much attention due to its selective recognition performance. In this study, cadmium imprinted maleic acid-co-acrylonitrile polymeric microsphere (Cd-I-MA-co-AN) was synthesized via precipitation polymerization using Cd(II) as tem...

4(4-nitrophenyl-zao)-2-(2-methoxy phenimino)-phenol and its coordination compounds with ni(ii), cu(ii), co(ii) and fe(iii) have been synthesized and characterized by elemental analyses, ft-ir, far-ir, near ir, uv-vis, mass spectrometry and molar conductivity and their electrochemical behaviours are reported.

The structure of the title compound, [Co(C(13)H(11)N(4)O)(2)(CH(3)OH)(2)], is a mononuclear six-coordinated octa-hedral cobalt(II) complex of C(i) mol-ecular symmetry. The Co(II) ion is coordinated by two N atoms and two O atoms from two 1,5-biphenyl-carbazide ligands, and two O atoms from two methanol molecules. Two diphenyl-carbazidate ligands and the central Co(II) ion form the basal plane, ...

The title compound, [Co(4)(C(4)H(4)O(5))(4)(C(7)H(6)N(2))(8)]·20H(2)O, consists of tetra-nuclear Co(II) complexes and disordered uncoordinated water mol-ecules. The tetra-meric complex mol-ecule has symmetry. While two benzimidazole mol-ecules and a tridentate malate dianion coordinate a Co(II) ion, the carboxylate O atom from an adjacent malate dianion bridges the Co(II) ions to complete a dis...

The asymmetric unit of the title compound, {[Co(3)Yb(2)(C(5)H(2)N(2)O(4))(6)(H(2)O)(4)]·2H(2)O}(n), contains one Yb(III) ion, two Co(II) ions (one situated on an inversion centre), three imidazole-4,5-dicarboxyl-ate ligands, two coordinated water mol-ecules and one uncoordinated water mol-ecule. The Yb(III) ion is seven-coordinated, in a monocapped trigonal prismatic coordination geometry, by s...
