Abstract: The organometallic dimers, [{R(CO2CH2C2H-mu)(2)}{CO2(CO)(6)}(2)] [R = C6H4-1,4 (1), (CH)(2) (2), (CH2)(2) (3)], have been prepared from reactions between CO2(CO)(8) and appropriate diyne ligands in tetrahydrofuran at room temperature. These complexes have been characterized by IR spectra, H-1 NMR spectra and elemental analyses. The structure of (1) was determined by single crystal X-ray diffraction. The compound (1), C26H10O16Co4, Mr = 814.06, is triclinic, space group P (1) over bar, with unit cell dimensions a = 8.139(2), b 8.803(3), c = 11.343(3) Angstrom, alpha = 99.421(6), beta = 96.260(6), gamma = 102.772(6)degrees. The cobalt atom is coordinated by three terminal carbon is and an alkynyl group. The Co-Co bond length is 2.4834(7) Angstrom.
