Structure, electrochemical and dynamic behavior of bis (pentamethylcyclopentadienyl) titanium (IV) dithiolene complexes

Cooperative reduction by Ln2+ and Cp*− ions: synthesis and properties of Sm, Eu, and Yb complexes with 3,6-di-tert-butyl-o-benzoquinone

“…There are two irreversible peaks of smaller intensity in the negative region for 1 and 2 (−0.45 and −0.60 V vs. Fc + /Fc), which can correspond to the reduction of the species obtained upon oxidation of Cp* ligands. 53 These irreversible oxidation and reduction peaks are absent in the case of 4, and, rather unexpectedly, in the case of 3; the latter fact cannot be ascribed to the insufficient concentration of Cp* ligands, since the concentration of complexes was maintained at the same level. Potentially, the reaction with the remaining water could lead to the partial removal of Cp* ligands owing to hydrolysis, but the preservation of the initial colour of the solutions during the CV experiments, and careful preparation of the solvent and solutions (similarly to the other complexes) does not support this supposition.…”

Syntheses and electrochemical characterization of heteroleptic cyclopentadienyl–dithiolene d2 tungsten complexes. Structures and magnetic properties of charge-transfer salts †

“…7, 17 The lower value observed in the case of 7 is attributable to the steric crowding induced by the substituted cyclopentadienyl as already demonstrated for [Ti(η-C 5 Me 5 ) 2 -(C 3 S 5 )]. 18 Note also that d 1 neutral compounds present a more important folding than do the d 1 cations as a consequence, may be, of the dithiolene contribution upon oxidation. Indeed, the higher the electron density on the metal, the less is the folding of the ligand.…”

Two Heteroleptic Cobalt(III) Cyclopentadienyl/Dithiolene Complexes

“…In the course of our work on electroactive materials built from heteroleptic cyclopentadienyl/dithiolene complexes with Ti, Nb and Mo (Fourmigu6 & Coulon, 1994;Fourmigu6, Lenoir, Coulon, Guyon & Amaudrut, 1995;Guyon, Fourmigu6, Audebert & Amaudrut, 1995;Guyon, Lenoir, Fourmigu6, Larsen & Amaudrut, 1990), we have been interested in the corresponding Co complexes of general formula CpCo(dithiolene), where Cp is the cyclopentadienyl ligand. The structures of such CO IlI complexes with various dithiolenes have been reported, e.g.…”
