  • Beschreibung: <jats:p>Tricarbonyl[9-(triphenylphosphonio)fluorenylidene]ruthenium, [Ru(C<jats:sub>31</jats:sub>H<jats:sub>21</jats:sub>P)(CO)<jats:sub>3</jats:sub>], (I), is mononuclear, consisting of a single Ru centre, to which three carbonyl units and a chelating μ<jats:sub>3</jats:sub>-9-(triphenylphosphonio)fluorenide ylide bind to generate a distorted octahedral RuC<jats:sub>6</jats:sub>core. Nonacarbonyl-μ<jats:sub>3</jats:sub>-fluorenylidene-μ<jats:sub>2</jats:sub>-hydrido-<jats:italic>triangulo</jats:italic>-triosmium(III), [Os<jats:sub>3</jats:sub>H(C<jats:sub>13</jats:sub>H<jats:sub>7</jats:sub>)(CO)<jats:sub>9</jats:sub>], (II), is trinuclear and presents a triangular triosmium core, nine carbonyl ligands and one fluorenylidene ligand. Two of the Os<jats:sup>III</jats:sup>centres present a highly distorted hexacoordinated Os(Os<jats:sub>2</jats:sub>C<jats:sub>4</jats:sub>) core and are in turn bridged by a hydride ligand. The remaining Os<jats:sup>III</jats:sup>cation is octacoordinated, with an Os(Os<jats:sub>2</jats:sub>C<jats:sub>6</jats:sub>) nucleus. The crystal structures of both compounds are the result of nondirectional forces, much resembling the packing of weakly interacting quasi-spherical units,<jats:italic>viz.</jats:italic>the molecules themselves in (I) and centrosymmetric π–π-bonded dimers in (II).</jats:p>
