  Reactions of dihalogenotriorgano-phosphorus, -arsenic and -antimony compounds with [Fe₂(CO)₉]. Single-crystal structures of the iron(III) complexes [(Ph₃PO)₂H][FeBr₄] and [Ph₄Sb][Fel₄]·Ph₃Sbl₂and of [Fe(CO)₃(Ph₃P)₂]

  摘要：

  The reaction of [Fe2(CO)9] with compounds of stoichiometry R3EX2 [R3E = Ph3P, (p-MeOC6H4)3P, Me2PhP, Me3As or Ph3Sb, X = I; R3E = Ph3P, Ph3As or Me3As, X = Br] has been investigated and shown to yield diverse products. A series of complexes with the ionic structure [R3EX][Fe(R3E)X3] [E = P, R3 = Ph3, Me2Ph or (p-MeOC6H4)3, X = I; R3E = Me3As; X = I or Br] has been obtained. The reaction of [Fe2(CO)9] with Ph3PBr2 and Ph3AsBr2, however, resulted in the formation of the iron(III) complexes [(Ph3E)2Br][FeBr4]. Hydrolysis of [(Ph3P)2Br][FeBr4] by trace quantities of water produces [(Ph3PO)2H][FeBr4], the crystal structure of which has been determined. Triphenylantimony diiodide reacted with [Fe2(CO)9] yielding the surprising ionic adduct [Ph4Sb][FeI4].Ph3SbI2, remarkable not only for the phenyl migration at the antimony atom, but also for the formation of the rare [FeI4]- anion from a zerovalent iron carbonyl complex. The reaction of [Fe2(CO)9] with the milder diphosphine tetraiodide, I2Ph2PCH2CH2PPh2I2, produced [Fe(CO)3(Ph2PCH2CH2PPh2)I][I3], a complex in which three CO ligands are retained.

  The stannylated ammonium salt [HN(SnMe3)(3)]I (1) originates from N(SnMe3)(3) and ISnMe3 in n-hexane, while [H2N(SnMe3)(2)][SnMe3Cl2] (2) is formed as a by-product by the conversion of N(SnMe3)(3) with Gallium(III)chloride in CCl4. The complex [N(AsMe3)(2)]Br (3) with pentavalent arsenic synthesized by reaction of AsMe3Br2 with N(SnMe3)(3) in diethyl ether. 1-3 were characterized by IR spectroscopy and by crystal structure analyses.1: Space group P2(1)3, Z = 8; lattice dimensions at -50 degrees C: a = b = c = 1558.7 pm. The structure consists of two symmetry independent ion pairs with N-H ... I hydrogen bridge contacts.2: Space group, Pca2(1), Z = 4; lattice dimensions at -60 degrees C a = 1373.2, b = 762.2, c = 1951.5 pm. The structure consists of [H2N(SnMe3)(2)](+) and [SnMe3Cl2](-) ions, which are associated to chains via interionic Sn ... Cl contacts.3: Space group I4(1)/a, Z = 8; lattice dimensions at -50 degrees C: a = b = 826.3, c = 3490.9 pm. 3 consists of bromide ions and cations [N(AsMe3)(2)](+) with short AsN distances of 175.1 pm along with an AsNAs bond angle of 122.1 degrees.
