Synthesis and characterization of Pentaaquo-4-pyridylchromium (III) ion
<p>4-bromopyridine hydrochloride is a compound which has a relatively high formal charge on the 4 carbon. Molecular orbital calculations on pyridine show a +0.18 charge on the 4 position, a +0.15 charge on the 2 position, and a +0.05 charge on the 3 position with the nitrogen holding a -0.59 …

THE EMISSION OF PYRIDINE AND POLYPYRIDINECHROMIUM(III) COMPLEXES IN RIGID AND FLUID MEDIA.
The excited state emissions and lifetimes of [Cr(bipy)₃]³⁺, cis – [Cr(bipy)₂Cl₂]⁺, trans – [Cr(py)₄FBr]⁺, cis – [Cr(phen)₂F₂]⁺, and trans – [Cr(py)₄F₂]⁺ were studied in hydroxylic and nonhydroxylic solvents at 77 K and as a function of temperature. The emission characteristics are determined by the …

The characterization and kinetics of N-formyl-N-methylaminomethenylpentaaquochromium(III) ion
… was the first to isolate a stable sigma bonded organochromium (III) complex.<sup>1</sup> This was the benzylpentaquochromium (III) ion obtained by the reduction of benzyl halide with chromium (II) perchlorate. The mechanism of this and similar reactions has been thoroughly studied and is …

Kinetics and stoichiometry of the aquation reaction of pentaaquomonobromomethylchromium (III) perchlorate
The purpose of this thesis was to determine the kinetics and stoichiometry for the aquation of the pentaaquomonobromonmethylchromium(III) complex. The complex was prepared by the reduction of dibromomethane by chromium(II). The products of aquation, in the absence of oxygen, were found to be …
