X-Ray diffraction study was carried out of the binuclear complex Re2(CO)7(C8H2Ph2Fc2) (II), obtained in the reaction of (OC)5ReC<*>CPh with ferrocenylacetylene FcC<*>CH in refluxing toluene.Complex II crystallizes in the monoclinic space group P21/n with a 20.363(5), b 10.121(2), c 22.952(7) Angstroem, β 112.49(2)o, V 4302(2) Angstroem3, and Z=4.Compound II possesses a rhenacyclopentadiene ring, fused with the methylenecyclopentene moiety along the central C-C bond, and ?-bonded by the Re(CO)3 group.The hydrocarbon ligand of compound II is formed by condensation of two PhC<*>C groups and two FcC<*>CH molecules.Preparative methods of synthesis of (OC)5ReC<*>CPh, (OC)5ReC<*>CCO2Me and (OC)5ReC<*>CSiMe3 are reported. Key words: Rhenium; Ferrocene; Alkyne; Carbonyl; Crystal structure
