([eta superscript 5]-Cyclopentadienyl)([eta superscript 6]-phenoxathiin 10,10-dioxide)iron(II) hexafluoridophosphate and phenoxathiin 10,10-dioxide

Abstract

In the structure of the title complex salt, [Fe(C[subscript 5]H[subscript 5])(C[subscript 12]H[subscript 8]O[subscript 3]S)]PF[subscript 6], the coordinated cyclopentadienyl (Cp) and benzene ring planes are almost parallel, with a hinge angle between the planes of 0.8 (2)°. The hinge angle between the planes of the peripheral (coordinated and uncoordinated) benzene rings in the coordinated phenoxathiin 10,10-dioxide molecule is 169.9 (2)°, and the FeCp moiety is located inside the shallow fold of the heterocycle. The hinge angle between the benzene ring planes in the free heterocycle, C[subscript 12]H[subscript 8]O[subscript 3]S, is 171.49 (6)°.
