The title complex, [Cd(2)(C(11)H(7)O(3))(4)(C(12)H(8)N(2))(2)]·4H(2)O, has a centrosymmetric binuclear structure in which two Cd(II) atoms are both six-coordinated and bridged by 6-hydroxy-naphthalene-1-carboxyl-ate ligands, with a Cd⋯Cd separation of 3.671 (1) Å. The remaining coordination sites are occupied by two N atoms of a 1,10-phenanthroline ligand and two O atoms of a 6-hydroxy-naphthal...

In the title dinuclear Cd(II) complex, [Cd(2)(C(2)N(4)O(2))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], each Cd atom is in a slightly distorted octa-hedral coordination by two N atoms and one O atom of two 1H-tetra-zole-5-carboxyl-ate (TZC) ligands, two N atoms of a 2,2'-bipyridyl ligand and one water O atom. The TZC ligand acts in a tridentate N,O-chelating N-bridging mode to two symmetry-equivalent Cd(I...

The title Cd(II) coordination polymer, catena-poly[[{1,4-bis-[1-(2-pyridylmeth-yl)benzimidazol-2-yl]butane}cadmium(II)]-μ-benzene-1,3-dicarboxyl-ato], [Cd(C(8)H(4)O(4))(C(30)H(28)N(6))](n), was obtained by reaction of CdCO(3), benzene-1,3-dicarboxylic acid (H(2)btc) and 1,4-bis-[1-(2-pyridylmeth-yl)benzimidazol-2-yl]butane (L). The Cd(II) cation is six-coordinated by an N(2)O(4)-donor set. L ac...

The structure of the title compound, [Cd(NCS)(2)(C(5)H(8)N(2))(4)], consists of isolated mol-ecules of [Cd(NCS)(2)(Eim)(4)] (Eim = 1-ethyl-imidazole), which contain a compressed octa-hedral CdN(6) chromophore. The NCS(-) anions are trans and four N atoms from the 1-ethyl-imidazole ligands define the equatorial plane. The mean Cd-N(Eim) and Cd-N(NCS) distances are 2.334 (4) and 2.379 (5) Å, resp...

The entrance of Cd (II) to aqueous environments causes a major problem to human health. The current article examines the efficiency of TiO2 and γ-Al2O3 nanoparticles in Cd (II) removal from aqueous medium as influenced by different chemical factors, such as pH, initial concentration, background electrolyte, and ionic strength, in accordance with standard experimental methods. It conducts Batch ...

In the title compound, [Cd(2)(C(6)H(8)O(4))(2)(C(16)H(20)N(4))(H(2)O)(4)](n), penta-gonal-bipyramidally coordinated Cd(II) ions are connected into {Cd(2)(2,2-dimethyl-succinate)(2)(H(2)O)(4)} centrosymmetric dimeric clusters. In turn, these clusters are linked by tethering 1,4-bis-(3-pyridylmeth-yl)piperazine (3-bpmp) ligands into [Cd(2)(2,2-dimethyl-succinate)(2)(3-bpmp)(H(2)O)(4)](n) coordina...

Mammalian metallothionein (MT) is Involved in the detoxiflcation of Cd(ll) ions. It binds 7 Cd(ll) in two Cd-thiolate clusters (Cd4S11 and C3S9) which are located in two protein domains. 111Cd and 2-D NMR studies show that in lobster, two Cd3S9 domains exist. Despite homologies in the location of cysteines between the corresponding domains of the lobster and mammalian MTs (8 of the 9 cysteines ...

A cadmium (8 mM) resistant Pseudomonas aeruginosa strain KUCd1 exhibiting high Cd accumulation under in vitro aerobic condition has been reported. The isolate showed a significant ability to remove more than 75% and 89% of the soluble cadmium during the active growth phase from the growth medium and from Cd-amended industrial wastewater under growth supportive condition. Transmission electron m...

The title compound, [Cd(NCS)(2)(C(12)H(8)N(2))(2)], has been obtained from the decomposition reaction of dithio-oxamide in a dimethyl-formamide solution containing 1,10-phenanthroline (phen) and Cd(NO(3))(2)·4H(2)O. Its crystal structure is formed by monuclear Cd(II) entities in which the metal atom is sited on a twofold rotation axis. The Cd(II) atom is six-coordinated in the form of a distort...

The title complex, [Cd(2)(C(8)H(7)O(3))(4)(C(20)H(22)N(4)O)(2)], forms a dimer of the paddle-wheel type, located on a crystallographic inversion centre. The Cd(II) ion is hexa-coordinated by four carboxylate O atoms [Cd⋯O = 2.280 (2)-2.404 (2) Å] from two chelating 4-methoxy-benzoate anions, and two N atoms [Cd⋯N = 2.313 (2) and 2.332 (2) Å] from one chelating 2,2'-dimethyl-3,3'-(oxydiethyl-ene...
