  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 X-ray crystal structures of dimeric ZnI 2 [P(NMe 2 ) 3 ]} 2 and monomeric ZnI 2 (PPh 2 Me) 2 are also described. The formation of the bis complexes ZnI 2 (PR 3 ) 2 (R 3 =Ph 3 , Ph 2 Me, Ph 2 Et) is surprising and cannot be due to steric factors since complexes containing less bulky tertiary

  The novel reaction of R3PI compounds with dicobalt octacarbonyl has been investigated and compared to previous studies involving the reaction of R3PI2 compounds with cobalt metal powders. The products produced from both reactions have identical stoichiometries but, surprisingly, possess different structures. Infrared and Raman spectroscopic studies and X-ray powder diffraction clearly show that the
