By the combination of different metal salts and solvents, four unprecedented in situ reactions have been discovered for heterocyclic disulfide of 2-ppds (2-ppds = di[4-(pyridin-2-yl)pyrimidinyl]disulfide). In the CH3CN-DMF solvent, reaction of 2-ppds with AgNO3 produced a one-dimensional chain structure of {[Ag2(1L)2]·2CH3CN}n (1), wherein 2-ppds was converted into its sulfonate of 1L by means ...

With no internal vibrational or rotational degrees of freedom, atomic solutes serve as the simplest possible probe of a condensed-phase environment's influence on solute electronic structure. Of the various atomic species that can be formed in solution, the quasi-one-electron alkali atoms in ether solvents have been the most widely studied experimentally, primarily due to the convenient locatio...

Extending carbon frameworks via a series of C-C bond forming reactions is essential for the synthesis of natural products, pharmaceutically active compounds, active agrochemical ingredients, and a variety of functional materials. The application of stereoselective C-C bond forming reactions to the one-pot synthesis of biorelevant compounds is now emerging as a challenging and powerful strategy ...

Porphyrin metal (Zn, Cu, and Mg) complex monolayer-protected gold nanorods (GNRs) were, for the first time, synthesized. Their synthesis was easy to access by mixing porphyrin encapsulated GNRs with corresponding excess soluble metal salts in solution, followed by the facile purification through centrifugation and sonication due to the gravity of the GNRs and their solubility in organic solvent...

metal complexes, but is useful in the case of metal complexes with low extractability. This process has thus been applied to the separation of metals, which is difficult by conventional batch extraction.1 Extraction reagents (HR) are usually consumed in amounts several hundred times those of metals (M). Complexes to be extractable into an organic solvent {MRn·(HR)m} are not always obtained usin...

X-ray absorption spectroscopy (XAS) was used to characterize the structure of photoactive Co(II) azobenzene complex. Optical spectra show that photoinduced changes occur only in dimethylformamide (DMF) solvent, while acetonitrile, this complex is photochemically inactive. Co K-edge XAS indicate 6-coordinated species acetonitrile with a similar one crystalline form However, DMF, an activation pr...

The synthesis and structural, magnetic and gas adsorption properties of a series of coordination polymer materials prepared from a new, highly flexible and internally functional tetrakis-carboxybenzyl ligand H4L derived from 1,2-diaminoethane have been examined. The compound poly-[Ni3(HL)2(OH2)4]·2DMF·2H2O 1, a two-dimensional coordination polymer, contains aqua- and carboxylato-bridged trinucl...

The implementation of four bidentate building blocks into a high-denticity linker with a flexible spacer leads to a predisposed ligand that allows one to direct the self-assembly of 1D functional coordination polymers. This is illustrated by the assembly under mild conditions of the luminescent metal-organic framework [Tb(Htpabn)] . 14H2O infinity (1; H4tpabn = N,N,N',N'-tetrakis[(6-carboxypyri...

The title compound, [Co(C13H9N2O2)2]·1.5C3H7NO, is formed as a neutral Co(II) complex with di-methyl-formamide (DMF) solvent mol-ecules. The Co(II) atom has a distorted O2N4 octa-hedral coordination sphere defined by two tridentate anionic Schiff base ligands with the O atoms being cis. The coordination sphere around the Co(II) atom is geometrically different from that reported for the co-cryst...

Computational chemistry has recently introduced the improved reaction field theory and now is capable of evaluating the bulk solvent effect quite accurately. It is time to expand this capability to mixed solvents, as it is often extremely useful through is still not well understood. For example, the determination of rates of complexations of divalent metal ions with a tridentate metal-ion indic...
