The crystal and molecular structure of the complex containing cobalt-carbon and iron-sulfur cluster cores,(μ-ρ-CH_3C_6H_4C_2S)(μ-n-C_3H_7S)Fe_2(CO)_6Co_2(CO)_6,has been determined byX-ray diffraction method.The crystals are triclinic,space group P,with a=9.139(2),b=9.610(1),c=17.183(2),α=84.36(1),β=89.45(1),γ=88.15(1)°,V=1501.0~3;Z=2,D_c=1.74 g/cm~3.R=0.072,Rw=0.081.The results of the structure determination show a cobalt-carbon clustercore formed through the reaction of(μ-ρ-CH_3C_6H_4C_2S)(μ-n-C_3H_7S)Fe_2(CO)_6 with Co_2(CO)_8.Inthe cobalt-carbon cluster core,the bond length of the original C≡C lengthened to 1.324 whichis close to the typical value of carbon-carbon double bond.The groups connecting the carbons ofthe cluster core are in cis position and lie on the opposite side of cobalt atoms.In this complex,theconformation of-SC_3H_7 is e-type,while that of-SC_2C_6H_4CH_3 is a-type.
The crystal and molecular structure of the complex containing cobalt-carbon and iron-sulfur cluster cores, (μ-ρ-CH 3 C_6H_4C_2S) (μn-C_3H_7S) Fe_2 (CO) _6Co_2 (CO) _6 has been determined by X-ray diffraction (2), α = 84.36 (1), β = 89.45 (1), γ = 88.15 (1) °, V = 1501.0~3; Z = 2, D_c = 1.74 g / cm~3.R = 0.072, Rw = 0.081. The results of the structure determination show a cobalt-carbon clustercore formed through the reaction of The bond length of the original C≡C lengthened to 1.324 whichis close to the typical value (μ-n-C_3H_7S) Fe_2 (CO) _6 with Co_2 (CO) of carbon-carbon double bond. The groups connecting the carbons of the cluster core are in cis position and lie on the opposite side of cobalt atoms. In this complex, the information of-SC_3H_7 is e-type, while that of-SC_2C_6H_4CH_3 is a- type.
