Structural characterization voltammetry

A number of these complexes have been structurally characterized (Table 14). The Os— N(N) bond lengths (1.846-1.915 A) are significantly shorter than Os—single bonds (2.039-2.123 A). The N—N bond lengths (1.231-1.321 A) are relatively short, consistent with a N=N double bond. The Os complexes exhibit reversible Os, Os, in cyclic voltammetry, and the... 

A few electrochemical studies have been also addressed to the structurally characterized (XRD ) VO(acac)2 ". It undergoes oxidation to [VO(acac)2]+ by a process which seems to be reversible in the short times of cyclic voltammetry, but coupled to chemical complications in the longer times of exhaustive electrolysis. One of its salts has been spectroscopically identified as [VO(acac)2](l5). VO(acac)2 also undergoes irreversible or partially reversible reduction processes, particularly in the presence of uncomplexed acac, which ultimately afford [V(acac)3] . The pertinent electrode potentials are listed in Table 8. 

A series of new metal aminocarbene-substituted Fp complexes have also been prepared starting from the above ethoxycarbene complex. Some examples of these binuclear aminocarbene complexes are shown in Scheme 38. The complexes were characterized by analytical and spectroscopic methods. Cyclic voltammetry was also used to investigate these binuclear aminocarbene compounds, and two complexes were structurally characterized by X-ray crystallography. 

Prior to the publication in 1980 of Clavilier s historic paper (1) reporting anomalous voltammetry of Pt(lll), there had been a number of studies of the voltammetry of single crystal Pt electrodes, with some using modern methods of surface analysis (e.g., LEED or RHEED) for characterization of the structure of the crystal prior to immersion in electrolyte (2-6). and all were in qualitative agreement with the seminal work (in 1965) on Pt single crystals by Will (7.). 

By today s standards of surface preparation, Will s procedures for surface preparation were crude, the surface structures were not characterized by use of surface analytical instrumentation (Which was neither widely available nor well developed at that time), and he employed extensive potentiodynamic cycling through the "oxide" formation potential region prior to reporting the quasi-steady state voltammetry curve, i.e., the potentiodynamic I-V curve. The studies employing surface analytical methods made a decade or more later were...

Similar chain molybdenum compounds [Mo2(02CCF3)4 L] (L = 9,10-antra-quinone or 2,6-dimethylbenzoquinone) were prepared and characterized by x-ray structure analyses, 13C-NMR spectra, and cyclic voltammetry [230,231], In case of use of 2,6-di-t-butyl- -benzoquinone (2,6-t-Bu-BQ), a / /,v-/ -quinone adduct [Mo2(02CCF3)4(2,6-t-Bu-BQ)2] was isolated [231],...
