Coordination chemistry spectroscopy

While 61Ni Mossbauer spectroscopy has proven valuable in solid-state chemistry, its application to problems in coordination chemistry is very rare. The parent 61Co nucleus (/ /2 99 min) serves as the...

Phosphacyclic diphosphines (73a) and (73b) with wide natural bite angles were synthesized and the effect of the phosphacyclic moieties on the coordination chemistry in the [(diphosphine) Rh(CO)2H] complexes was studied. Both NMR and IR spectroscopy showed that the phosphacyclic xantphos ligands exhibit an enhanced preference for diequatorial chelation compared to the diphenylphosphino-substituted parent compound. In the hydroformylation of 1-octene the introduction of the phosphacyclic moieties leads to higher reaction rates. The dibenzophospholyl- and phenoxaphosphino-substituted xantphos ligands exhibit a high activity and selectivity in the hydroformylation of trans-2- and 4-octene to linear nonanal. CO dissociation rates from the...

The purpose of this brief survey was to demonstrate that, despite the criticisms which may be made of the use of any semi-empirical quantum technique for structural and conformational studies, the CNDO/2 and Extended CNDO/2 formalisms are definitely reliable tools for theoretical conformational analyses in inorganic and coordination chemistry. Moreover, if these tools are combined with the most suitable experimental techniques (i.e. microwave spectroscopy and electron diffraction) in that field, many problems of geometry and conformation can be solved in a way that neither of these approaches could have accomplished alone. 

He was sent by the Japanese Government to Europe in 1910. He first stayed in the laboratory of A. Hantzsch in Leipzig, and soon moved to the laboratory of A. Werner (1866-1919) in Zurich to leam Coordination Chemistry. He also stayed in the laboratory of G. Urban of the University of Paris to study spectroscopy. He returned from Europe in 1913 with a spectrometer made by Adam Hilger Co. in England, which is the first equipment to be able to measure spectra of solution in Japan, and he used the equipment for the measurements of spectra of coordination... 

Study of Coordination Chemistry and Biochemicals Using Mossbauer Spectroscopy... 

Dr. Erickson For those interested in coordination chemistry, certain other transition metal atoms are suitable for Mossbauer spectroscopy. One in particular is ruthenium which is just below iron in the Periodic Table. It is a difficult isotope to work with since it requires helium temperatures almost exclusively. I don t know whether it is possible to work at nitrogen temperatures or not, but Kistner at Brookhaven has examined various ruthenium compounds from the 2-j- to the 8+ oxidation states with interesting results. These are not published yet, but at least his work offers the possibility of going down one element below the other in the Periodic Table to study chemical effects. Osmium, which is below ruthenium, can also be Mossbauered. Some sort of systematic study like this involving elements in the various transition series would be extremely interesting. 

The solubility and coordination properties of uranium(VI) in ILs sfrongly depend on fhe chemical form of the uranium(VI) induced in solution, the composition of ILs, and fhe presence of any other anions [7]. The coordination chemistry of iron(III) fefraarylporphyrins in ILs studied by UV-Vis spectroscopy could be mentioned [8].
