In the title complex, [Zn(C(12)H(18)N(2)O)I(2)], the Zn(II) ion is four-coordinated by the imine N and amine N atoms of the Schiff base ligand and by two iodide ions in a distorted tetra-hedral coordination.

In the title compound, [ZnBr(2)(C(17)H(14)Cl(4)N(2))], the Zn(II) ion is bonded to two bromide ions and two N atoms of the diimine ligand and displays a moderately distorted tetra-hedral coordination geometry. The Schiff base ligand acts as a chelating ligand and coordinates to the Zn(II) atom via two N atoms.

A naphthalimide based fluorescent probe has been synthesized which shows ratiometric fluorescence response towards Zn(2+) ions and the in situ prepared -Zn(2+) complex was used for the detection of pyrophosphate and hydrogen peroxide which mimics the functions of sequential logic circuits at the molecular level.

In the title compound, [Zn(C(8)H(16)NS(2))(2)], the Zn(II) atom is chelated by two S,S'-bidentate dithio-carbamate ions in a very distorted tetra-hedral geometry. The alkyl chains of the ligands are equally disordered over two sets of sites.

The title compound, [Zn(2)(C(42)H(38)N(9)O(3))(2)(NO(3))(2)]·2CH(3)CN·0.5H(2)O, is a bis-phenolate-bridged dinuclear Zn(II) complex. The asymmetric unit comprises half the zinc complex (the full complex is completed by the application of a centre of inversion), one acetonitrile solvent mol-ecule and a quarter of a water mol-ecule (located on a twofold axis with half-occupancy; H atoms were not ...

The orientation-dependent structural properties of Zn(1-x)Mg(x)O nanorods with different Mg concentrations were investigated quantitatively using polarization-dependent extended X-ray absorption fine structure (EXAFS) measurements at the Zn K edge. Vertically-aligned Zn(1-x)Mg(x)O nanorods were synthesized on Si substrates using catalyst free metal organic chemical vapor deposition. Polarizatio...

The present work comprises the recombinant synthesis of four metallothioneins (MTs) in metal-unsupplemented cultures and the characterization of the recovered metal complexes by means of analytical and spectrometric techniques. The four MTs are two Drosophila (MtnA and MtnB), one yeast (Crs5), and one mouse (mMT1) metallothionein isoforms. These four MTs exhibit distinct metal binding preferenc...

Single spinel phases of Mn0.5Ni0.1Zn0.4Nd x Fe2- x O4 ferrite samples (x = 0.0, 0.01, 0.02, 0.05, 0.075, and 0.1) have been prepared by ceramic method and the composition dependence of the physical and magnetic properties has been investigated. SEM micrographs and EDX analysis revealed that there is no considerable effect for the Nd(3+) ion substitution on the average grain size or porosity, wh...

ABSTRACT A high yield preparation, spectroscopic and crystallographic investigation of the crystalline Zn-complex of a di(β,β'-sulfoleno)pyrrin are reported here. In the brightly green fluorescent Zn-complex of the hardly luminescent di(β,β'-sulfoleno)pyrrin, the metal ion is bound by two di(β,β'-sulfoleno)pyrrin ligands, as revealed first by its mass spectra. The crystal structure of this Zn-c...

We examine the self-assembly of a peptide A6H comprising a hexa-alanine sequence A6 with a histidine (H) "head group", which chelates Zn(2+) cations. We study the self-assembly of A6H and binding of Zn(2+) ions in ZnCl2 solutions, under acidic and neutral conditions. A6H self-assembles into nanotapes held together by a β-sheet structure in acidic aqueous solutions. By dissolving A6H in acidic Z...
