摘要

A new family of CuX-, Cu₂X₂-, and Cu ₄X₂-incorporated mono- or di-SeFe₃-based carbonyl clusters were constructed and structurally characterized. When the selenium-capped triiron carbonyl cluster [Et₄N]₂[SeFe ₃(CO)₉] was treated with 1-3 equiv of CuX in tetrahydrofuran (THF) at low or room temperatures, CuX-incorporated SeFe ₃ complexes [Et₄N]₂[SeFe₃(CO) ₉CuX] (X = Cl, [Et₄N]₂[1a]; Br, [Et ₄N]₂[1b]; I, [Et₄N]₂[1c]), Cu ₂X₂-incorporated SeFe₃ clusters [Et ₄N]₂[SeFe₃(CO)₉Cu₂X ₂] (X = Cl, [Et₄N]₂[2a]; Br, [Et ₄N]₂[2b]), and Cu₄X₂-linked di-SeFe₃ clusters [Et₄N]₂[{SeFe ₃(CO)₉}₂Cu₄X₂] (X = Cl, [Et₄N]₂[3a]; Br, [PPh₄]₂[3b]) were obtained, respectively, in good yields. SeFe₃CuX complexes 1a and 1b were found to undergo cluster expansion to form SeFe₃Cu ₂X₂ complexes 2a and 2b, respectively, upon the addition of 1 equiv of CuX (X = Cl, Br). Furthermore, complexes 2a and 2b can expand further to form Cu₄X₂-linked di-SeFe₃ clusters 3a and 3b, upon treatment with 1 equiv of CuX (X = Cl, Br). [Et ₄N]₄[{SeFe₃(CO)₉(CuCl) ₂}₂] ([Et₄N]₄[4a]) was produced when the reaction of [Et₄N]₂[SeFe₃(CO)₉] with 2 equiv of CuCl was conducted in THF at 40°C. The Cu ₂Cl₂-linked di-SeFe₃CuCl cluster 4a is a dimerization product derived from complex 2a. Further, it is found that complex 4a can convert to the Cu₄Cl₂-linked di-SeFe₃ cluster 3a upon treatment with CuCl. The nature, formation, stepwise cluster expansion, and electrochemical properties of these CuX-, Cu₂X ₂-, and Cu₄X₂-incorporated mono- or di-SeFe₃-based clusters are elucidated in detail by molecular calculations at the B3LYP level of the density functional theory in terms of the effects of selenium, iron, copper halides, and the size of the metal skeleton.
