چکیده
In the structure of the title compound, [Fe{η(5)-C(5)(CH(3))(5)}(NCCH(3))(CO)(2)]BF(4), the arrangement of ligands around the Fe atom is in a pseudo-octa-hedral three-legged piano-stool fashion in which the penta-methyl-cyclo-penta-dienyl (Cp*) ligand occupies three apical coordination sites, while the two carbonyl and one acetonitrile ligands form the basal axes of the coordination. The Fe-N bond length is 1.924 (3) Å and the Fe-Cp* centroid distance is 1.722 Å.

In the title compound, [Fe(C(10)H(15))(C(6)H(12)N(4))(CO)(2)]BF(4), the arrangement around the Fe(II) atom corresponds to a three-legged piano stool. The penta-methyl-cyclo-penta-dienyl (Cp*) ligand occupies three coordination sites, while two CO ligands and one N atom of the hexa-methyl-ene-tetra-mine ligand occupy the remaining coordination sites, completing a pseudo-octahedral geometry. Both...

The asymmetric unit of the title compound, [Fe(2)(C(5)H(5))(2)(C(2)H(8)N(2))(CO)(4)](BF(4))(2), contains two half-cations, each located on a center of symmetry, and two tetra-fluorido-borate anions. The iron atoms adopt a three-legged piano-stool geometry. All amine H atoms are involved in N-H⋯F hydrogen bonds, which consolidate the crystal packing along with weak C-H⋯O and C-H⋯F inter-actions.
