In this paper, the structure of mixed cluster (C_5H_5FeC_5H_4C_2Ph) Co_2 (CO) _6 was studied by electrochemical method and X-ray single crystal structure analysis. From the results of cyclic voltammetry, the bonding properties of C_5H_5FeC_5H_4 and C_2Co_2 centers in clusters were discussed respectively. The X-ray single crystal structure analysis showed that the crystal belongs to monoclinic system with space group P2_1, unit cell parameter a = 11.845 (6) (C_5H_5FeC_5H_4C_2Ph) Co_2 · (C_5H_5FeC_5H_4C_2Ph), b = 8.155 (6), c = 24.031 (6), β = 90.88 ° and the number of molecules in unit cell Z = 4 and density D 0 = 1.637g · cm -3 (CO) _6. The structure of (RC_2R ~ 1) Co_2 (CO) _6 clusters with RC_2R ~ 1 was discussed from the perspective of bond formation.
