Abstract

The synthesis, spectroscopic characterization and X-ray crystal structure of a new chiral triosmium alkylidyne carbonyl cluster, (R,S)-[Os ₃(μ-H)₂(CO)₉{μ₃-CPPh ₂(η⁵-C₅H₄)Fe(η⁵- C₅H₃(PPh₂)CH(Me)NMe₂)}] (1) are described. Compound 1 crystallizes in the non-eentrosymmetric space group P2₁ and its absolute configuration has been established. The structure consists of an Os₃C metal core with one of the PPh ₂ moieties of the chiral ferrocenylphosphine bonded to the apical alkylidyne carbon atom to give a zwitterionic cluster complex, reminiscent of the phosphorus ylide.
