The title compounds, tetrabenzyl-2κC,3κC,4κC,5κC-octa-μ3- chloro-bis (tributylphosphine) - 1κP,6κP-octa-hedro-hexamolybdenum (12 Mo-Mo), (1), and tetra-kis(phenylethynyl)-2κC,3κC,4κC,5κC-octa-μ 3-chloro-bis(tripentylphosphine)-1κP,6κP-octahedr o-hexamolybdenum (12 Mo-Mo)-toluene (1/2), (2), containing octahedral Mo clusters with four σ-C ligands, were prepared by the reaction of trans-[(Mo6Cl8)Cl4(PR3)2] with tribenzylaluminum and tris(phenylethynyl)aluminum, respectively, and their structures determined. The octahedral Mo6 cores of both compounds are on inversion centres and are almost regular. Average interatomic distances in the clusters for (1) are Mo-MOedge 2.618, MO···Moopposite 3.703, Mo-Cl 2.477 and Mo-C 2.26 angstroms, and for (2) are Mo-Moedge 2.626, Mo···Moopposite 3.714 and Mo-C 2.13 angstroms.
