Abstract

Trivalent uranium complexes supported by tris(aryloxide) chelating ligands, [(( ArO) tacn)U] and [(( ArO) N)U], undergo activation of sulfur and selenium in their elemental forms, generating the mid-valent U(iv)/(U(iv) complexes of the type [{(( ArO) tacn)U} (μ-E)] and [{(( ArO) N)U} (μ-E)] (E = S, Se). Under reducing conditions, [(( ArO) N)U] reacts with elemental sulfur, selenium and tellurium to yield the mid-valent dinuclear bis-μ-chalcogenide complexes [Na(DME) ] [{(( ArO) N)U} (μ-E) ] (E = S, Se, Te) with the diamond-core structural motif and rare inorganic chalcogenide bridging ligands. For comparison, a unique high-valent U(v)/U(v) dinuclear complex [{(( ArO) N)U} (μ-O) ] was also synthesized. A short uranium-uranium distance in this complex with a U(μ-O) U diamond-core may account for the unusual temperature-dependent magnetic behavior. © The Royal Society of Chemistry 2011.
