چکیده
In the structure of the title compound, [Fe(C(5)H(5))(C(6)H(12)N(4))(CO)(2)]BF(4), the arrangement around the Fe(II) atom corresponds to that of a three-legged piano stool. The cyclo-penta-dienyl ligand occupies three coordination sites of the apical position in a η(5) fashion, while two CO ligands and one N atom of the hexa-methyl-ene-tetra-mine ligand occupy the remaining coordination sites to complete a distorted octa-hedral geometry. The asymmetric unit consists of two sets of crystallographically independent cations and anions with the r.m.s. deviations of the overlay of non-H atoms of each pair being 0.081 and 0.120 Å, respectively. The Fe-N bond lengths are 2.0459 (15) and 2.0490 (14) Å, while the Fe-Cp(centroid) distances are 1.7257 (3) and 1.7246 (3) Å. One of the anions displays disorder, with the F atoms having occupancies of 0.58 (4) and 0.42 (4).
