([eta superscript 5]-Cyclopentadienyl)[[eta superscript 6]-diethyl ethyl(phenyl)malonate]iron(II) hexafluoridophosphate

Abstract

At 223 (2) K, the complexed rings in the iron(II) complex cation of the title salt, [Fe(C[subscript 5]H[subscript 5])(C[subscript 15]H[subscript 20]O[subscript 4])]PF[subscript 6], are almost parallel [dihedral angle between planes = 4.10 (14)°]. Among the C atoms of the complexed arene ring, the quaternary C atom is located at the longest distance from the Fe atom. The F atoms of the PF[subscript 6[superscript minus sign]] anion were found to be equally disordered over two sites.
