Dicarbonyl (η5-cyclopentadienyl)(hexamethylenetetramine-κN1) iron (II) tetrafluoridoborate
M'thiruaine, Cyprian M; Friedrich, Holger B; Omondi, Bernard (International Union of Crystallography, 2012)In the structure of the title compound, [Fe(C5H5)(C6H12N4)-(CO)2]BF4, the arrangement around the FeIIatom corresponds to that of a three-legged piano stool. The cyclopenta-dienyl ligand occupies three coordination sites ... -
[HTML] from iucr.org (μ-Formato-κ2O: O′) bis [dicarbonyl (η5-cyclopentadienyl) iron (II)] tetrafluoridoborate.
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 ... -

M’thiruaine, Cyprian M.; Friedrich, Holger B.; Nyawade, Eunice A.; Omondi, Bernard (Inorganica Chimica Acta, 2014)The new 2,4,6-trimethylaniline complexes [Cp∗Fe(CO)2(NH2C6H2(CH3)3)]+ (3) and [CpFe(CO)2(NH2C6H2(CH3)3)]+ (4) (Cp∗ = η5-C5(CH3)5; Cp = η5-C5H5) have been synthesized and isolated in high yields as tetrafluoroborate salts. ... -
Syntheses, structural elucidation and reactions of allylamino compounds of the type, [η5-C5R5(CO)2Fe(NH2CH2CHCH2)]BF4
M’thiruaine, Cyprian M; Friedrich, Holger B; Changamu, Evans O; Omondi, Bernard (Pergamon, 2012)The reaction of 3-aminoprop-1-ene (allylamine) with the etherate complexes [(n5-C5R5)(CO)2Fe(L)]+(R = H; L = Et2O; R = CH3; L = THF) have been investigated and found to give air stable allylamino com-plexes [(n5-C5R5)(CO ... -
Synthesis, characterization and crystal structures of two polymorphs of the iodo-bridged ruthenium salt, μ-iodido-bis {η 5-cyclopentadienyl-dicarbonyl-ruthenium (II)} tetrafluoroborate
Nyawade, Eunice A; Friedrich, Holger B; M’thiruaine, Cyprian M; Omondi, Bernard (Elsevier, 2013)The reaction of RpI (Rp = (η5-C5H5)Ru(CO)2) and AgBF4 in two different solvents, tetrahydrofuran and dichloromethane afforded two polymorphs of the iodo-bridged cationic complex [Rp2I]BF4. Polymorph I precipitates out of ... -
