  摘要：

  The reactions of compound Rh-2(CO)(4)Cl-2, 1 with [Co-2(CO)(6)(mu-HC2CH2O)-](2)R (R = C6H4, 2; (COCH2)(2), 3; C6H4-1,4-(CO)(2), 4; (COCH)(2), 5; (CO)(2), 6) in benzene at 60 degrees C produce five new mixed-metal linked clusters Rh2CO2(CO)(10)(mu(4),eta(2) -HC2CH2O-R-OCH2C2H-mu) OCH2C2H-mu) (R = C6H4, 7a; (COCH2)(2), 7b; C6H4-1,4-(CO)(2), 7c; (COCH)(2), 7d; (CO)2, 7e) and five known linked octahedral clusters [Rh2Co2)(CO)(10)(mu(4)eta(2)-HC2CH2O-)](2)R (R = C6H4, 8a; (COCH2)(2), 8b; C6H4-1,4-(CO)(2), 8c; (COCH)(2), 8d; (CO)(2), 8e), respectively. Treatment of clusters 7a-8e in benzene at room temperature under air for 24 h with stirring afford the precursor clusters 2-6, respectively. The structure of cluster 7a has been determined by single-crystal X-ray diffraction. The linked cluster 7a possesses two isomers A and B in its structures, the Rh-2(CO)(4) unit inserts into one of two Co-Co bonds and coordinates to the Co2C2 core forming one distorted closo-Rh2CO2C2 octahedron framework which is connected to the Co2C2 tetrahedron unit via C6H4(OCH2)(2)-1,4 as a bridging ligand. All clusters were characterized by C, H elemental analysis, IR and H-1 NMR spectroscopy. (c) 2005 Published by Elsevier B.V.

  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.
