SOLID-STATE AND SOLUTION STRUCTURE OF (BPY)CUCO(CO)4 (BPY = 2,2'-BIPYRIDINE) Academic Article uri icon

abstract

  • The heterobimetallic complex (bpy)CuCo(CO)4has been prepared by the reaction of NaCo(CO)4with 2,2=bipyridine and CuCl in dichloromethane and has been characterized by X-ray crystallography at -80 C. The complex crystallizes in the monoclinic space group P2l/a, with unit cell dimensions a = 7.210 (3) , b = 16.580 (6) , c = 11.912 (6) , = 97.88 (4), V= 1410 ( 1 ) , Z = 4, and RF= 3.34%. The Cu-Co bond distance was found to be 2.404 ( 1 ) and to be supported by an asymmetrically bridged carbonyl ligand. This bridging CO group persists in polar solvents as well, as indicated by a v(CO) band at 1850 cm-1in the infrared spectra in both THF and Nujol mull. On the other hand, the CuCo bond is disrupted by a facile reaction at -78 C with dppe (l,2-bis(diphenylphosphino)ethane) to provide the Co(CO)4- anion and Cu(bpy)(dppe)+. 1990, American Chemical Society.
