Reactions of the tetrahedral methylantimony complex [Et4N]2[MeSb{Fe(CO)4}3] with HOAc and [Cu(MeCN)4][BF4] were investigated. While the reaction of [Et4N]2[MeSb{Fe(CO)4}3] with HOAc forms the substituted complex [Et4N][Me(OAc)-Sb{Fe(CO)4}2] ([Et4N][I]), the treatment with [Cu(MeCN)4][BF4] forms the oxidized product [MeSb{Fe(CO)4}{Fe2(CO)8}] (II). The structures of [Et4N][I] and II are determined by single-crystal X-ray diffraction. [Et4N][I] crystallizes in the orthorhombic space group Pna21 with a = 16.627(4), b = 9.411(3), c = 17.347(4) Å, V = 2714(1) Å3, and Z = 4. The crystals of II are triclinic, space group P1 with a = 9.335(1), b = 10.313(3), c = 10.372(1) Å, α = 97.46(1), β = 93.63(1), γ = 94.65(1)°, V = 984.0 (3) Å3, and Z = 2. Cluster I is an OAc group substituted product which displays a tetrahedral metal core with the central antimony atom bonded to two Fe(CO)4 fragments, one Me group, and one OAc moiety. Compound II is the two-electron oxidized product of [Et4N]2[MeSb{Fe(CO)4}3] where one Fe-Fe bond is formed upon the addition of [Cu(MeCN)4][BF4]. The results are compared with those of the analogous bismuth system and the role of the main group elements is discussed as well.
