Tris(μ2-carbonyl)octacarbonyl(triphenylphosphite)tetracobalt

Abstract

In toluene solution, the reaction of [Co2(CO)8] with an equimolar amount of [P(OPh)3] yields first [Co2(CO)7{P(OPh)3}] 1. Following heating of 1, an alternative synthetic access to the tetranuclear cluster [{Co4(μ2-CO)3(CO)8{P(OPh)3}] 2 is provided in a condensation reaction. Compound 2 has been characterized by IR and 31P NMR spectroscopy. The tetranuclear cluster framework has been ascertained by a single-crystal X-ray diffraction study performed at 100 K.

Crystal structure and Hirshfeld surface analysis of a halogen bond between 2-(allylthio)pyridine and 1,2,4,5-tetrafluoro-3,6-diiodobenzene

“…The structural motif of thioethers is also well known, especially in the context of ligand chemistry with silicon-based thioethers for palladium (Schneider et al, 2023;Bastero et al, 2002) or silver (Nomiya et al, 1996;Gaudillat et al, 2023). Sulfonium-based ionic liquids (Zhao et al, 2007) and other systems like (Z)-3-allyl-5-(4-nitrobenzylidene)-2-sulfanylidene-1,3-thiazolidin-4-one (Moreno et al, 2024) are good examples of compounds with allyl groups.…”
