[(5a,6,7,8,9,9a-[eta superscript 6])-[l,4]Benzodioxinol[2,3-b]- pyridine]([eta superscript 5]cyclopentadienyl)iron(II) hexafluorophosphate

Abstract

The structure of [(5a,6,7,8,9,9a-[eta superscript 6])-[1,4]benzodi-oxino[2,3-b]pyridine]([eta superscript 5]-cyclopentadienyl)iron(II)hexafluorophosphate, [Fe(C[subscript 5]H[subscript 5])(C[subscript 11] H[subscript 7]NO[subscript 2])]PF[subscript 6], has been studied. The dihedral angle between the benzene and pyridine rings of the ligand system is 177.4 (3)°; the benzene and cyclopentadienyl rings are nearly parallel [dihedral angle 1.3 (4)°]. The Fe atom is closer to the benzene ring [1.542 (4) [Angstrom]] than to the cyclopentadienyl (Cp) ring [1.652 (5) [Angstrom]] and it is located within the fold of the heterocyclic ligand.
