      From a mechanistic point of view, the use of nanoparticles as catalysts requires analysis of the catalytically active species in terms of their agglomeration and the leaching of the molecular species. This aspectbecomes crucial for work under “wet” catalytic conditions. The present review focuses on the nature of palladium nanoparticle catalysts that are either preformed or generated in situ.

      Synthesis, characterization, and photophysical properties of new Re(CO)3Cl complexes containing 1-pyridylimidazo[1,5-a]pyridine ligands are presented. The complexes display high-energy singlet emissions arising from a π [RIGHTWARDS ARROW] π* ligand-centered state and intense ligand-centered triplet emission in oxygen-free acetonitrile solutions. The nature of the excited states was analyzed by using TDDFT methods.

      An organic–inorganic hybrid was found to undergo reversible structural transition under moderate conditions leading to a polymorph phase. Conformational changes in the disulfide molecules in the solid state resulted in an abrupt decrease in the second harmonic generation (SHG) intensity; thus, this material can be considered as an SHG switch controlled by temperature.

      Two coordination polymers based on the light-weight metal magnesium were prepared by solvothermal synthesis. One of these is microporous with a large porevolume, high apparent surface area, and potentially accessible metal sites. Framework, thermal stability, and behavior upon dehydration and re-hydration indicate that it is a suitable adsorbent.

The geometry at antimony is distorted octahedral, with evidence for a stereochemically active lone pair. The reaction of SbI3 with dtbtu produces a 1:1 complex, [SbI3(dtbtu)].
