摘要 : The reaction of Cd(CH3COO)(2)center dot H2O with di-2-pyridyl ketone (DPK) and FcCOONa in methanol-acetonitrile led to the formation of a tetranuclear ferrocene-cadmium compound [Cd-4(eta(2)-FcCOO)(3)(FcCOO)(DPD-OH)(4)]center dot ... 展开 The reaction of Cd(CH3COO)(2)center dot H2O with di-2-pyridyl ketone (DPK) and FcCOONa in methanol-acetonitrile led to the formation of a tetranuclear ferrocene-cadmium compound [Cd-4(eta(2)-FcCOO)(3)(FcCOO)(DPD-OH)(4)]center dot 2CH(2)CI(2)center dot FcCOOH (Fc=(eta(5)-C5H5)Fe(eta(5)-C5H4), DPD-OH-=(2-PY)(2)C(OH)O-). In the compound three of the four coordinated ferrocenecarboxylates behave as chelating ligands, while the other one acts as a monodentate ligand. Each of them is linked to one Cd(II) ion via the coordination of the carboxylate group. The four Cd(II) ions mentioned above are further consolidated by four DPD-OH- anions functioning as eta(1):eta(3):eta(1):mu(3) ligands to form a Cd4O4 cubane. The thus formed title compound shows a strong fluorescent emission at ca. 576 nm in the solid state. (c) 2006 Elsevier B.V. All rights reserved. 收起
