Abstract

Reduction of tungsten hexacarbonyl by the divalent samarium(II) complex [Sm₂(N₄Et₈)(thf)₄] ((N₄Et₈)⁴⁻=meso-octaethylcalix[4]pyrrolide) in toluene at ambient temperature gave the remarkable heteronuclear mixed-valent samarium(II/III)/tungsten complex [{(thf)₂Sm^II(N₄Et₈)Sm^III(thf)}₂{(μ-OC)₂W₂(CO)₈}], which features the trapping of a rare [W₂(CO)₁₀]²⁻ anion with an unsupported W−W bond.
