In the title compound, [Cu(C(8)H(4)O(4))(C(3)H(4)N(2))(2)](n), the Cu(II) atom is four-coordinated by two carboxyl-ate O atoms from two different terephthalate ligands and two N atoms from two imidazole ligands in a slightly distorted square-planar coordination environment. Each terephthalate ligand acts as a bis-monodentate ligand that binds two Cu(II) atoms, thus forming two unique chains ext...

In the title coordination polymer, {[Zn(C(9)H(7)NO(4))(C(10)H(14)N(4))]·2H(2)O}(n), the Zn(II) ion displays a distorted tetra-hedral geometry with two imidazole N atoms from two 1,1'-(butane-1,4-di-yl)bis-(imidazole) (bbi) ligands and two carboxyl-ate O atoms from two 2,6-dimethyl-pyridine-3,5-dicarboxyl-ate (dpdc) ligands. The bbi and dpdc ligands bridge the Zn(II) ions, forming layers paralle...

The centrosymmetric mol-ecule of the title complex, [Cd(4)Cl(8)(C(3)H(4)N(2))(6)(C(3)H(7)NO)(2)], contains four Cd(II) atoms, six imidazole, two dimethyl-formamide and eight chloride ligands. The structure shows a novel chloride-bridged tetra-nuclear cadmium quasi-cubane cluster. The coordination geometry of all Cd(II) atoms is distorted octa-hedral, with the two metal atoms in the asymmetric u...

In the polymeric title compound, [CdCl2(C6H6N4)] n , the central CdII atom is coordinated by four chloride ligands and two N atoms from a chelating 2,2'-bi-1H-imidazole mol-ecule, leading to a distorted octa-hedral Cl4N2 coordination set. As a result of the μ2-bridging character of the Cl ligands, chains parallel to the c axis are formed, with the chelating 2,2'-bi-1H-imidazole ligands decorate...

The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely d...

Our goal was to explore the possible interactions of potential metallodrug (η5-Cp*)Rh(III) complexes with histidine containing biomolecules (peptides/proteins) in order understand most important thermodynamic factors influencing biospeciation and biotransformation complexes. To this end, here we report systematic solution structural study on interaction cation peptides their constituents ((N-me...

In the title compound, {[Ag(C(10)H(14)N(4))(H(2)O)](C(14)H(8)O(4))(0.5)·2H(2)O}(n), the Ag(I) ion is three-coordinated by two N atoms from two independent 1,1'-(butane-1,4-di-yl)di-1H-imidazole (BBI) ligands and one water O atom in a distorted T-shaped coordination geometry. The biphenyl-4,4'-dicarboxyl-ate (BPDC) dianions do not coordinate to Ag(I) ions but act as counter-ions. The Ag(I) ions ...

The preparation of a number of agarose and polyacrylamide bead derivatives useful in the purification of proteins by afhnity chromatography is described. These techniques permit (a) the attachment of ligands to the gel through extended hydrocarbon chains which place the ligand at varying distances from the gel matrix backbone; (b) the covalent attachment of ligands to agarose or polyacrylamide ...
