Iron and Ruthenium Heterobimetallic Carbonyl Complexes as Electrocatalysts for Alcohol Oxidation: Electrochemical and Mechanistic Studies

“…Heterobinuclear complexes have long been investigated as catalysts, due to the potential for reactivity different from that of their mononuclear analogues. − In such species, the two metals can work cooperatively or each can perform a different task which leads to an overall increase in activity. − …”

Monocationic μ-Diborolyl Triple-Decker Complexes [CpCo(μ-1,3-C3B2Me5)M(ring)]+: Synthesis, Structures, and Electrochemistry

“…As follows from the Cambridge Crystallographic Database, for the complexes [(C 5 R 5 )Ru(C 6 R 6 )] + (R = H, Alk) an analogous situation is observed. For example, the shortest Ru···arene and Ru···Cp* distances were observed in [(C 5 Me 5 )Ru(C 6 H 6 )] + (1.703 and 1.809 Å, respectively) and the longest in [(C 5 Me 5 )Ru(η 6 -5,6-dipropyl-2,3-dihydro-1 H -indene)] + (1.742 and 1.841 Å, respectively) …”

“…Selected parameters for these structures and for the previously described 13 3bPF 6 , 4bPF 6 , and 5bPF 6 are given in Table 1 (see also Table S1 in the Supporting Information for selected bond lengths and angles). 1.809 Å, respectively) 20 and the longest in [(C 5 Me 5 )Ru(η 6 -5,6dipropyl-2,3-dihydro-1H-indene)] + (1.742 and 1.841 Å, respectively). 21 Analysis of intermolecular contacts indicates that cations 4a are arranged in chains by weak π(C(sp 2 ))−π(C(sp 2 )) stacking interactions Cp(Co)•••Cp(Ir) (ca.…”

Syntheses and Properties of Triruthenium Polyhydrido Complexes Composed of 1,2,4-tri-tert-butylcyclopentadienyl and p-Cymene Ruthenium Units

“…Severin et al reported that a mixed-ligand trichlorido-bridged diruthenium complex, [Cp*Ru­(μ-Cl) 3 Ru­( p -cymene)], is formed quantitatively upon mixing [Cp*RuCl] 4 and [( p -cymene)­RuCl 2 ] 2 . , On the basis of their observations, we succeeded in the exclusive preparation of a corresponding trihydrido-bridged diruthenium complex, [Cp ‡ Ru­(μ-H) 3 Ru­( p -cymene)] ( 2a ), using the 2-propanol/base method (Scheme a) . However, when [(C 6 H 6 )­RuCl 2 ] 2 was employed, a mixture of mixed-ligand di- and triruthenium complexes, [Cp ‡ Ru­(μ-H) 3 Ru­(C 6 H 6 )] ( 2b ) and [(Cp ‡ Ru) 2 {(C 6 H 6 )­Ru}­(μ-H) 4 (μ 3 -H)] ( 3b ), was obtained.…”
