Dicarbonyl(hexamethylene-1,3,5,7-tetramine-κN1) (η5-pentamethylcyclopentadienyl)iron(II) tetrafluoridoborate

Abstract

In the title compound, [Fe(C10H15)(C 6H12N4)(CO)2]BF4, the arrangement around the FeII atom corresponds to a three-legged piano stool. The pentamethylcyclopentadienyl (Cp*) ligand occupies three coordination sites, while two CO ligands and one N atom of the hexamethylenetetramine ligand occupy the remaining coordination sites, completing a pseudo-octahedral geometry. Both the complex cation and the BF 4- anion reside on crystallographic mirror planes. The Fe - N bond length is 2.069 (2) and the Fe - Cp*(centroid) distance is 1.7452 (3) Å. © 2012 International Union of Crystallography.
