Dicarbonyl (hexamethylene-1, 3, 5, 7-tetramine-κN1)(η5-pentamethylcyclopentadienyl) iron (II) tetrafluoridoborate
M'thiruaine, Cyprian M; Friedrich, Holger B; Changamu, Evans O; Fernandes, Manuel A (International Union of Crystallography, 2012)In the title compound, [Fe(C10H15)(C6H12N4)(CO)2]BF4, the arrangement around the FeIIatom corresponds to a three-legged piano stool. The pentamethylcyclopentadienyl (Cp*) ligand occupies three coordination ... -

M'thiruaine, Cyprian M; Friedrich, Holger B; Changamu, Evans O; Omondi, Bernard (International Union of Crystallography, 2011)In the structure of the title compound [Fe(2)(C(5)H(5))(2)(CHO(2))(CO)(4)]BF(4), each Fe(II) atom is coordinated in a pseudo-octa-hedral three-legged piano-stool fashion. The cyclo-penta-dienyl ligand occupies three fac ... -
Regioselective reactions of electrophilic iron dicarbonyl cations, [(η5-C5R5)(CO)2Fe]+ (R = H, CH3) with heterofunctional amine ligands
M M’thiruaine, Cyprian; Friedrich, Holger B; Changamu, Evans O; Omondi, Bernard (Elsevier, 2012)The reactions of the ether salts [(η5-C5R5)(CO)2Fe(E)]BF4, (R = H, E = Et2O; R = CH3, E = THF) with various ligands possessing two different coordination sites have been investigated. It was established that [(Cp(CO)2Fe(OEt2)]BF4 ... -
A structural investigation of the D2O solvated, acetone solvated and nonsolvated 1,4-Diazabicyclo[2.2.2]octane complexes of the half sandwich moiety [(η5-C5H5)(CO)2Fe]
Changamu, Evans O; Omondi, Bernard; M'thiruaine, Cyprian M; Friedrich, Holger B (Sabinet, 2013)Two new solvates of the dinuclear salt {(η5-C5H5)(CO)2Fe}2(μ-DABCO)](BF4)2 (DABCO = 1,4-diazabicyclo[2.2.2]octane); 1 (D2O solvate) and 2 (acetone solvate), and the mononuclear salt [(η5-C5H5)(CO)2Fe(DABCO)]BF4, 3, have ... -
