The title compound, [Zn(C(8)H(4)O(4))(C(13)H(14)N(2))](n), was obtained by the hydro-thermal reaction of Zn(OAc)(2)·H(2)O with 1,3-di-4-pyridylpropane (bpp) and isophthalic acid (H(2)ip). The Zn(II) ion is coordinated by two bpp and two ip ligands in a distorted tetra-hedral environment. Each ligand coordinates in a bridging mode to connect Zn(II) ions into a three-dimensional diamondoid-type s...

In the title compound, [Zn(C(8)H(5)O(3))(2)(C(6)H(6)N(2)O)](n), the Zn(II) ion is tetrahedrally coordinated by two formyl-benzoate (FB) and one isonicotinamide (INA) ligands while symmetry-related FB ligands bridge adjacent Zn(II) ions, forming polymeric chains along the b axis. The carboxyl-ate groups in the two FB ions are twisted away from the attached benzene ring by 9.07 (2) and 26.2 (2)°....

In this work ternary CdZnS thin films were prepared by chemical bath deposition by doping CdS with different concentrations of Zn ions. The chemical bath comprised of cadmium nitrate [Cd(NO3)2], as a source of Cd 2+, zinc nitrate [ZnNO3)2]as source of Zn 2+ , thiourea [(NH2)2CS] as a source of sulphide ions [S 2]in the presence of ammonia [NH3] as a complexing agent. The competition mechanisms ...

We synthesized a new Pt/Zn-based coordination polymer, {Zn[Pt(CN)(2)(5,5'-dcbpy)].4H(2)O}(n), (5,5'-H(2)dcbpy = 5,5'-dicarboxy-2,2'-bipyridine), which exhibits reversible colour changes in response to temperature change or exposure to chemical vapours and liquids. Such chromic behaviour shows promise for sensing not only changes in temperature but also for detecting chemical solvents and vapour...

A novel polyfunctional dipodal ligand, L = N,N'-bis[2-[(2-hydroxy-1-naphthyl)methyleneamino]ethyl]propanediamide (DOTA2HNAP) was developed and characterized through elemental and spectral analyses. The complexation behavior of the ligand was investigated with Co2+, Cu2+, and Zn2+ metal ions by potentiometric and spectrophotometric methods in H2O-D...

Since zinc ions play an important role in various physiological activities, developing a facile detection method for Zn(2+) is highly desirable. Owing to their superior optical properties, semiconductor quantum dots (QDs) have been developed as a promising alternative for organic fluorophores in fluorescence analysis. In this study, water soluble di-2-picolylamine-dithiolcarbamate (DPA-DTC)/pro...

A simple and low cost chemosensor is described. This sensor could simultaneously detect three biologically important metal ions through fluorogenic (Zn(2+)) and chromogenic (Fe(2+), Cu(2+), and Zn(2+)) methods in aqueous solution. The sensor could function as a "turn-on" fluorescence receptor only to Zn(2+) ions. In addition, the sensor could be successfully applied to the detection of intracel...

In the present study a novel imine-hydrazone based fluorescent chemosensor () for efficient and selective sensing of Zn(2+) over other biologically important metal ions under physiological conditions is reported. An enhancement in fluorescence emission intensity of the developed probe with a red shift of ∼25 nm was observed for Zn(2+), whereas other metal ions failed to reveal any significant c...

The asymmetric unit of the title compound, [Zn(C(2)H(8)N(2))(3)]Cl(2)·H(2)O, contains a discrete [Zn(C(2)H(8)N(2))(3)](2+) cation with a distorted octa-hedral geometry around Zn, two uncoordinated chloride ions and one water mol-ecule. The crystal structure exhibits N-H⋯O, N-H⋯Cl and O-H⋯O hydrogen bonds.

The Schiff base 2-[(4-methyl-phen-yl)imino-meth-yl]-6-methoxy-phenol (HL) forms a complex with a Zn(2+) atom and two independent thio-cyanate ions, [Zn(NCS)(2)(C(15)H(15)NO(2))(2)], in which two phenolate O atoms the two independent Schiff base ligands are coordinated to thee Zn(2+) atom. The protonated imine N atoms are involved in an intramolecular hydrogen bond with the phenoxide group. The ...
