A synthetic route for the formation of 2-[bis(2-trifluoromethylphenyl)phosphinoylmethyl]pyridine N-oxide (1c) and 2-[bis(3,5-trifluoromethylphenyl)phosphinoylmethyl]pyridine N-oxide (1d) was developed and the new ligands characterized by spectroscopic methods and single-crystal X-ray diffraction analyses. The coordination chemistry of 1c was examined with Yb(NO3)3 and the molecular structure of...

Fluorous chemistry has brought many applications from catalysis to separation science, from supramolecular materials to analytical chemistry. However, fluorous-based quartz crystal microbalance (QCM) has not been reported so far. In the current paper, fluorous interaction has been firstly utilized in QCM, and carbohydrate-protein interaction and carbohydrate-carbohydrate interaction have been d...

The first explanation of spin-crossover in iron(II) complexes was published in Chem. Commun. in 1966. This has led to nearly 50 years of research in coordination chemistry, crystal engineering, solid state chemistry and physics, and nanoscience involving this class of molecular switch.

Structural Entities in Complex Oxides While materials at low temperatures are often characterized in terms of crystal chemical concepts, descriptions of their high-temperature properties are usually based on defect chemistry. Both approaches are obviously of great value but also have clear limitations. While the defect chemistry is often weakly linked to the crystal structure of the material an...
