Anion Assisted Redox Rates Between Cobalt (Ii) - Cobalt (Iii) Polypyridyl Complexes In Acetophenone, Seyed Garmestani
Anion Assisted Redox Rates Between Cobalt (Ii) - Cobalt (Iii) Polypyridyl Complexes In Acetophenone, Seyed Garmestani
Masters Theses & Specialist Projects
The effects of ionic strength and various anions on the rate of electron transfer between tris(2,2'-dipyridine) cobalt(III) and bis(2,2',2"-tripyridine) cobalt(II) complexes have been examined in acetophenone. The redox rate was found to increase with increasing ionic strength in both the presence and absence of added salts. The reaction was first order with respect to each reactant and second order overall in all cases. The influence of the C104, BF4, and B(C6H5)4 anions on the reaction rate was studied with their order of effectiveness being: C104- > BF4 >> B(C6 …
Electronic Transitions Of Metal Complexes With Triphenylphosphine As A Ligand, Thomas Zimmer
Electronic Transitions Of Metal Complexes With Triphenylphosphine As A Ligand, Thomas Zimmer
Masters Theses & Specialist Projects
The spectra of transition metal complexes with triphenylphosphine have been measured near 260 nm and the results interpreted in terms of perturbation of the it electron system of the phenyl ring. All complexes studied show sou degree of delocalization of the d-orbital electrons of the metal into the phenyl ring. However, for first row transition metals, the primary affect was found to be polarization of the phenyl ring due to the presence of the metal ion. For second and third row transition metal ions, the primary effect was found to be metal-ligand back-bonding. However, the effect of polarization of the …
A Spectrophotometric Equilibrium Study Of Nickel(Ii)-3, 4', 4", 4'"-Tetrasulfophthalocyanine, Stephen Lowery
A Spectrophotometric Equilibrium Study Of Nickel(Ii)-3, 4', 4", 4'"-Tetrasulfophthalocyanine, Stephen Lowery
Masters Theses & Specialist Projects
There have been several studies made on the effects of various central metal ions on the aggregation of tetrasulfonated Phthalocyanine dye complexes in aqueous solution, but there have been no studies made on the aggregation of the nickel(II)-4, 4', 4", 4'"-tetrasulfoohthalocyanine (NiII-TSPC) complex. Therefore, a study of the effects of nickel(II) on the aggregation of its aqueous tetrasulfonated Phthalocyanine dye complex was Proposed so that a comparison might be made with nrevious studies of central metal ion effects. It was found, however, that NiII-TSPC gives a much higher degree of aggregation in water than the metal …
