In the title complex, [Cu(C(12)H(15)Cl(2)N(2)O)(2)], the Cu(II) ion is coordinated by one N,O-bidentate and one N,N',O-tridentate Schiff base ligand, resulting in a distorted CuN(3)O(2) square-based pyramidal coordination for the metal ion, with the O atoms lying trans to each other in the basal plane.

lini0.5co0.5vo4 has been successfully synthesized by tartate precursor combustion method using li2co3, co(no3)2.6h2o, ni(no3)2.6h2o and nh4vo3 as a starting materials in deionized water with the subsequent calcination at 450-600 oc for 12 h. the combustion and decomposition of tartate precursor were studied by tga and compared with tartaric acid. it found weight loss at 50-450 oc. the product s...

The long-range base pairing between the 5BSL3. 2 and 3'X domains in hepatitis C virus (HCV) genomic RNA is essential for viral replication. Experimental evidence points to the critical role of metal ions, especially Mg2+ ions, in the formation of the 5BSL3.2:3'X kissing complex. Furthermore, NMR studies suggested an important ion-dependent conformational switch in the kissing process. However, ...

Methylene-bridged calix[4]arenes have emerged as extremely versatile ligand supports in the formation of new polymetallic clusters possessing fascinating magnetic properties. Metal ion binding rules established for this building block allow one to partially rationalise the complex assembly process. The ability to covalently link calix[4]arenes at the methylene bridge provides significantly impr...

a thermodynamic study on the interaction between zinc ion (zn2+) and human growth hormone(hgh) was studied at two temperatures of 27c and 37c in aqueous solution using an isothermal titrationcalorimetry. it was found that there is a set of three identical and non-interacting binding sites for zn2+ ions. the intrinsic dissociation equilibrium constant and the molar enthalpy of binding are 1.54...

Systematic cascading of molecular logic gates is an important issue to be addressed for advancing research in this field. We have demonstrated that photochemically triggered metal ion signals can be utilized towards that goal. Thus, independent logic gates were shown to work together while keeping their identity in more complex logic designs. Communication through the intermediacy of ion signal...

The production of metal hydrides in vapour phase is one of the problems which makes their spectroscopic investigation at high resolution difficult. The molecular densities are usually low and the absorption is often increased by the use of multipass cells or intracavity setups. In this contribution a discharge tube with coaxial geometry is investigated, which is able to produce relatively high ...

The ability to exchange reversibly the regulatory light chains (RLCs) from scallop myosin has provided us with a test system to probe the mechanisms of regulation mediated by the RLCs from vertebrate skeletal, vertebrate smooth and molluscan myosins. The cloning and expression of these RLCs, together with domain-swapping and site-directed mutagenesis approaches, has allowed us to explore furthe...
