The centrosymmetric dinuclear cadmium title complex, [Cd(2)(C(6)H(18)N(4))(3)](ClO(4))(4), was obtained by the reaction of N,N'-bis-(2-amino-eth-yl)ethane-1,2-diamine (trien) with Cd(NO(3))(2)·4H(2)O and sodium perchlorate in methanol. The Cd(II) cation is coordinated by four N atoms of a non-bridging trien ligand and by two N atoms of a bridging trien ligand in a slightly distorted octa-hedral...
In the crystal structure of the title compound, {[Cd(C(2)Cl(3)O(2))(2)(C(12)H(10)N(2))(2)]·H(2)O}(n), the Cd(II) ion lies on a twofold rotation axis and 1,2-bis-(4-pyrid-yl)ethene ligands bridge symmetry-related Cd(II) ions, forming a two-dimensional structure. Two trichloro-acetate ligands complete the coordination around the Cd(II )ion, forming a distorted octa-hedral environment. In the crys...
In the mol-ecular structure of the title neutral binuclear complex, [Cd(2)(C(2)H(3)O(2))(4)(C(12)H(12)N(2)O)(4)]·4H(2)O, each Cd(II) atom is six-coordinated and exhibits a distorted octa-hedral geometry. Three O atoms from two acetate ions and one monodentate 3-(1H-imidazol-1-yl-κN(3))-1-phenyl-propan-1-one (L) ligand form the equatorial plane, while the bridging-O atom forming the longer Cd-O ...
In this study, Groenlandia densa (L.) Fourr. (opposite-leaved pondweed), was exposed to prepared stock solution of cadmium and copper with 1.0, 3.0, 5.0 and 7.0 mg L(-1) concentration in certain periods (24, 48, 72 and 96 h) and changing amount of accumulation of plants in depending on time and concentration was measured by atomic absorption spectrophotometer. The results show that under experi...
Hydrothermal reactions of Cd(OAc)2·2H2O with a flexible V-shaped bipyridyl benzene ligand and five benzenedicarboxylic acid derivatives gave rise to five new coordination polymers i.e., [Cd(1,4-BDC)(bpmb)(H2O)]n (1), {[Cd(1,3-BDC)(bpmb)]·0.125H2O}n (2), [Cd2(5-Me-1,3-BDC)2(bpmb)2]n (3), [Cd(5-NO2-1,3-BDC)(bpmb)(H2O)]n (4) and [Cd(5-OH-1,3-BDC)(bpmb)(H2O)]n (5) (bpmb = 1,3-bis(pyridine-3-ylmetho...
The title complex, [Cd(2)(NO(3))(4)(C(24)H(16)N(6))(CH(4)O)(2)], displays a centrosymmetric dinuclear structure, in which the 2,3,5,6-tetra-2-pyridinylpyrazine (tppz) ligand links two Cd ions separated by 7.323 (4) Å. Each Cd(II) center is seven-coordinated by three N-atom donors of tppz in one plane, by two O atoms nearly normal to this plane, and by two O atoms 0.393 (3) and 0.488 (3) Å from ...
The title coordination polymer, {[Cd(2)(C(8)H(4)O(5))(2)(C(14)H(8)N(4))(2)]·2H(2)O}(n), has a layered structure. The asymmetric unit contains two Cd(II) ions, two pyrazino-[2,3-f][1,10]phenanthroline, two 5-hy-droxy-isophthalate (hip) ligands and two lattice water mol-ecules. Each Cd(II) ion is coordinated by two N atoms from a chelating pyrazino-[2,3-f][1,10]phenanthroline and four O atoms fro...
Cyclo-hexa-phospho-ric acid (P(6)O(18)H(6)) reacts with cadmium carbonate and 4-chloro-benzyl-amine (CBA) to give the mononuclear title complex, (C(7)H(9)ClN)(4)[Cd(P(6)O(18))](n), in which the Cd(II) atom, lying on an inversion centre, has an octa-hedral coordination built of six O atoms of two centrosymmetric P(6)O(18) rings. Each P(6)O(18) ligand acts as a bridge, linking two Cd(II) atoms an...
