Carotenes are naturally abundant unsaturated hydrocarbon pigments, and their fascinating physical and chemical properties have been studied intensively not only for better understanding of the roles in biological processes but also for the use in artificial chemical systems. However, their metal-binding ability has been virtually unexplored. Here we report that β-carotene has the ability to ass...

Recent advances in cooperative chemistry have shown the enormous potential of main group heterobimetallic complexes for functionalisation aromatic molecules. Going beyond metal chemistry, here we provide an overview on synthesis, structure and reactivity bimetallic which combine alkali-metal (AM= Li, Na) with a divalent earth-abundant transition (M= Mn, Fe, Co, Ni), containing utility silyl ami...

Heterobimetallic complexes containing M–C–E linkages (M = transition metal atom; E main group metal) have been postulated as relevant intermediates in cross-coupling reactions. Despite this, structural data for these species are scarce. In this contribution, we explore the coordination of E–C bonds (E Zn, Mg, Al) to Mo atoms dimolybdenum quadruple Mo–Mo bonds. addition, reactivity bis(hydride) ...

Stable germanium(II) and lead(II) amido complexes {LO(i)}M(N(SiMe3)2) (M = Ge(II), Pb(II)) bearing amino(ether)phenolate ligands are readily available using the proteo-ligands {LO(i)}H of general formula 2-CH2NR2-4,6-tBu2-C6H2OH (i = 1, NR2 = N((CH2)2OCH3)2; i = 2, NR2 = NEt2; i = 3, NR2 = aza-15-crown-5) and M(N(SiMe3)2)2 precursors. The molecular structures of these germylenes and plumbylenes...

Two heterobimetallic Ru(II)-Os(II) complexes of compositions [(bpy)2M(II)(phen-Hbzim-tpy)M'(II)(tpy-PhCH3)](4+), where M(II) = Ru and M'(II) = Os (4) and M(II) = Os and M'(II) = Ru (5), phen-Hbzim-tpy = 2-(4-(2,6-di(pyridin-2-yl)pyridine-4-yl)phenyl)-1H-imidazole[4,5][1,10]phenanthroline, bpy = 2,2'-bipyridine, and tpy-PhCH3 = 4'-(4-methylphenyl)-2,2':6',2''-terpyridine have been synthesized an...
