[[eta superscript 6]-1-Chloro-2-(pyrrolidin-1-yl)-benzene]([eta superscript 5]-cyclopentadienyl)iron(II) hexafluoridophosphate and ([eta superscript 5]-cyclopentadienyl){2-[[eta superscript 6]-2-(pyrrolidin-1-yl)-phenyl]phenol}iron(II) hexafluoridophosphate

Abstract

In the complex salt [eta superscript 6]-1-chloro-2-(pyrrolidin-1-yl)benzene]-([eta superscript 5]-cyclopentadienyl)iron(II) hexafluoridophosphate, [Fe(C[subscript 5]H[subscript 5])-(C[subscript 10]H[subscript 12]CIN)]PF[subscript 6], (I), the complexed cyclopentadienyl and benzene rings are almost parallel, with a dihedral angle between their planes of 2.3 (3)°. In a related complex salt, ([eta superscript 5]-cyclopentadienyl){2-[[eta superscript 6]-2-(pyrrolidin-1-yl)phenyl]phenol}-iron(II) hexafluoridophosphate, [Fe(C[subscript 5]H[subscript 5])(C[subscript 16]H[subscript 17]NO)]PF[subscript 6], (II), the analogous angle is 5.4 (1)°. In both complexes, the aromatic C atom bound to the pyrrolidine N atom is located out of the plane defined by the remaining five ring C atoms. The dihedral angles between the plane of these five ring atoms and a plane defined by the N-bound aromatic C atom and two neighboring C atoms are 9.7 (8) and 5.6 (2)° for (I) and (II), respectively.
