摘要：

The reaction of Cb*Co(CO)(2)I (1) (Cb* is tetramethylcyclobutadiene) with sodium phenyltelluride afforded the mononuclesar complex Cb*Co(CO)(2)TePh (2). The reaction of the latter with W(CO)(5)(THF) produced the Cb*Co(CO)(2)TePh[W(CO)(5)] compound (4). The reaction of 1 with the Cp2Cr2(SCMe3)(2)S complex gave the heterometallic cluster Cb*Co(mu(3)-S)(2)Cr(2)Cp2 (mu-SCMe3) (5). Complexes 2, 4, and 5 are diamagnetic. Their structures were determined by X-ray diffraction. Complex 2 contains the Co-Te bond (2.585(1) angstrom); complex 4, the Co-Te (2.558(8) angstrom) and W-Te (2.8467(6) angstrom) bonds. Complex 5 has the stable triangular sulfide-and tert-butylmercaptide-bridged core Cr2Co (Cr-Cr and Cr-Co bond lengths are 2.626(2) and 2.673(2) angstrom, respectively) with Cp ligands at the chromium atoms and a Cb* ligand at the cobalt atom. Complex 5 was characterized by cyclic voltammetry. The thermolysis of complex 4 was studied.
