摘要

When the tellurium-capped tri-iron carbonyl cluster [Et₄N] ₂[TeFe₃(CO)₉] was treated with 1 equiv of CuX In THF at O °C, CuX-incorporated clusters [Et₄N] ₂[TeFe₃(CO)₉CuX] (X= Cl, [Et₄N] ₂[1a]; Br, [Et₄N]₂[1b]; I, [Et ₄N]₂[1c]) were formed, respectively. X-ray analysis showed that 1a-1c each exhibited a TeFe3 core with one Fe-Fe bond bridged by one CuX fragment. When the reactions were carried out at a molar ratio of 1:2 (X= Cl, Br) or 1:3 (X= I) In tetrahydrofuran (THF) or MeCN at O °C, Cu ₂X₂-lncorporated clusters [Et₄N] ₂[TeFe₃(CO)₉Cu₂X₂] (X= Cl, [Et₄N]₂[2a]; Br, [Et₄N]₂[2b]; I, [Et₄N]₂[2c]) were obtained, respectively. Cluster 2a was structurally characterized by X-ray analysis to display a TeFe₃ core, In which one TeFe₂ plane was asymmetrically bridged and capped by one μ₃-CuCl and another μ₄-CuCI with two Cu atoms bonded. Complexes 1a-1c underwent skeleton expansion to form Cu ₃Xincorporated di-TeFe₃ clusters [(TeFe ₃(CO)₉}₂Cu₃X]^2- (X= Cl, 3a; Br, 3b; 1,3c), respectively, upon treatment with 1 equiv of [Cu(MeCN) ₄][BF₄] at O °C. X-ray analysis snowed that 3b and 3c each consisted of two TeFe3 clusters that were linked by a Cu₃X moiety. However, a similar reaction for 1a and 1b with 1 equiv of [Cu(MeCN) ₄][BF₄] at room temperature produced Cu₄X ₂-llnked di-TeFe3 clusters [(TeFe₃(CO)₉} ₂Cu₄X₂]^2- (X= Cl, 4a; Br, 4b). Cluster 4a was shown by X-ray analysis to have two TeFe3 cores linked by a Cu₄Cl₂ moiety. Clusters 4a and 4b were also produced directly from the reaction of [Et₄N]₂[TeFe ₃(CO)₉] with 4 equiv of CuX (X= Cl, Br) In THF. Furthermore, the nature, the formation, the cluster transformation, and the electrochemistry of the CuX-incorporated mono- or di-TeFe₃ clusters are explained in terms of the effects of tellurium, copper hallde, and the size of the metal skeleton, all of which are elucidated by molecular calculations at the B3LYP level of density functional theory.
