Mononuclear mixed-anions Mn complex of TPAMn(η-NO3)(η-ClO4), where TPA is tris(2-pyridylmethyl)amine, has been synthesized and characterized. The neutral TPAMn(η-NO3)(η-ClO4) was obtained from the reaction between Mn(NO3)2·4H2O and [H3TPA](ClO4)3 in MeOH. X-ray crystallographic structure of mononuclear TPAMn(η-NO3)(η-ClO4) complex showed a seven-coordinated geometry with a tripodal tetradentate...
the mononuclear complex [cu(l)(ch3cn)(pph3)]clo4, (1), (l= 2,5-diphenyl-3,4-bis(2-pyridyl)cyclopenta-2,4-dien-1-one), has been synthesized and investigated by elemental analysis, ir, 1h nmr, uv-vis spectroscopic methods and x-ray diffraction. the complex crystallizes in the non-centrosymmetric space group p212121 in accord with the asymmetric (atropisomer) cu centre. its coordination polyhedron...
Abstract Within this work, we report the results of nuclear inelastic scattering experiments low-spin phase iron(II) mononuclear SCO complex Fe[HBpz 3 ] 2 and density functional theory based calculations performed on a model molecule complex. We show that calculated partial vibrational states structure single center which is linked by three pyrazole rings to borat in good accordance with experi...
The title compound, [FeCl2(C12H26N4)]PF6, is the first mononuclear Fe3+ complex of an ethylene cross-bridged tetraaza-macrocycle to be structurally characterized. Comparison with the mononuclear Fe2+ complex of the same ligand shows that the smaller Fe3+ ion is more fully encapsulated by the cavity of the bicyclic ligand. Comparison with the mu-oxo dinuclear complex of an unsubstituted ligand o...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
