Abstract

[Os₅C(CO)₁₄]^2- was synthesized in 65% yield on the surface of MgO by treatment of adsorbed [Os₃(CO)₁₂] in CO. High-resolution transmission electron microscopy (HRTEM) indicated that the nanoclusters were nearly monodisperse and in the size range consistent with [Os₅C(CO)₁₄]^2-. The supported [Os₅C(CO)₁₄]^2- was decarbonylated in helium, giving supported nanoclusters that are well approximated as Os₅C, as shown by HRTEM and EXAFS data. Decarbonylation in H₂ gave larger clusters of osmium, as shown by HRTEM.
