Zur Struktur des Cycloheptatrienid-tricarbonyl-eisen(0)-Anions, [C7H7Fe(CO)3]– / The Structure of the Cyeloheptatrienide Triearbonyl Iron(O) Anion, [C7H7Fe(CO)3]-

Abstract

Abstract The crystal structure of the [C7H7Fe(CO)3]- anion stabilized with the [(C6H5)4As]+ cation has been determinated by X-ray diffraction. The crystals are monoclinic, space group P21/n. The unit cell with lattice constants a = 1607.9 pm, b = 1386.8 pm, c = 1249.1 pm and β - 91.52° includes four formula units. The Fe(CO)3 group is bonded to the allyl anion part of the C7H7 ring system, while the diene part is unco-ordinated.
