What is Synthesis of 1-(1-Ferrocenylethyl)-pyridinium Chloride and Its Hybrid Materials with Lindquist-type Polyoxometalates about?
A new ferrocene derivative, 1-(1-ferrocenylethyl)-pyridinium (fep 1⁄4 CpFeCpeCH(CH 3 )ePy þ ) chloride, and two charge-transfer salts (CTSs) based on the cationic fep donor and Lindqvist-type polyoxometalate acceptors, [fep] (2), were synthesized. fepCl was characterized by elemental analysis, IR spectroscopy and 1 H NMR and the two CTSs were characterized by elemental analysis, IR spectroscopy, UVevis diffuse reflectance spectrum, cyclic voltammetry, fluorescence spectrum and single crystal X-ray diffraction. X-ray crystallographic studies of the brownish red CTSs 1 and 2 reveal that they are isostructural and crystallize in the monoclinic space group P2 1 /n. In salts 1e2, fep and polyoxoanions are cocrystallized by Coulombic forces, and there also exist the complex CeH/p and p/p stacking interactions between the adjacent fep cations and CeH/O hydrogen bonds between the adjacent fep cations and polyanions. The UVevis diffuse reflectance spectra indicate the presence of a broad charge-transfer band between 500 and 850 nm for 1e2, and CT character of 1 and 2 is also confirmed by the Mulliken correlation between the CT transition energies and the reduction potentials of the polyoxom
