| 摘 要： | Friedel-Crafts acylation of α-thienyl phenylacetylenedicobalt hexacarbonyl with acetyl chlo-ride has been investigated. The results showed thiophene nucleus to be somewhat more reactivein the electrophilic acylation than benzene nucleus and benzene nucleus in turn to be morereactive than acylated thiophene nucleus. Through the acylation two new cobalt- carbon clustercomplexes, i. e. α'-acetyl-α -thienyl phenylacetylenedicobalt hexacarbonyl Ⅰ and α'- acetyl-α-thienyl P- acetylphenylacetylenedicobalt hexacarbonyl Ⅱ, were synthesized. The single crystalstructure of Ⅱ was determined as well as the structures of Ⅰ and Ⅱ were elucidated in termsof combustion analysis, IR and ~1HNMR spectroscopy. The crystal structure of Ⅱ belongsto the monoclinic system, space group Pz_1/n; cell parameters a = 8 .037(2), b = 16 .347(3),c = 17.823(2)A, β= 102.68(2)°, D_c = 1.61g·cm~(-3), Z = 4, and the final factor R = 0.040.
