Multiple Bonds Between Main-Group Elements and Transition Metals, LXXXII. - Dinuclear μ-Benzylidyne Complexes Having a Double Bond between Rhenium Atoms

The dialkylrhenium(V) complex (η5-C5Me5)Re(=O)(CH2Ph)2 (3) reacts with the organotitanium reagents (η5-C5H5)TiX3 (X = Cl, Br) to yield the dinuclear rhenium(IV) complexes (η5-C5Me5)2Re2X3(CC6H5) (4a,b).According to the single-crystal X-ray diffraction analysis, 4a'(C5Me4Et in place of C5Me5) represents one of the few known examples of μ-alkylidyne complexes that have metal-to-metal multiple bonds.The molecule of C2 symmetry has a planar four-membered Re,Cl,Re',Cl-ring geometry and two trans-oriented sets of ligands.Very small angles at the bridging chloro ligand and alkylidyne carbon atom result from the short metal-metal distance (double bond).
