Popis:	p-[(CO)9Co3C]2C6H4 (1) has been synthesized by reacting Co2(CO)8 with p-(Cl3C)2C6H4. 4,4′-[(OC)9Co3CC(O)]C6H4-C6H4[C(O)CCo3(CO)9] (2) has been synthesized from p-LiC6H4-C6H4Li and BrCCo3(CO)9. Similarly m-[(OC)9Co3CC(O)CH2]2C6H4 (3) has been synthesized from m-(LiCH2)2C6H4 and BrCCo3(CO)9. X-ray analysis was done for 1 and 2; both compounds exhibit a stacked structure. Cyclic voltammetry and UV spectra revealed usual behavior for 1, that is, two cluster units interact strongly through the benzene spacer, which is not the case for clusters 2 and 3.
